Digitrax

The Digitrax DH187A0 is a drop-in light board replacement for HO locomotives - you unscrew the factory DC light board and this Series 7 decoder takes its place, keeping the original lighting positions. It is the standard fit for many Kato, Athearn Genesis and Stewart models, and it brings eight FX7 function outputs at 300mA, far more lighting capability than a two-function decoder. Building a DCC fleet? Browse our DCC Decoders, DCC Speakers, and DCC Accessories. Features Drop-in light board replacement - swaps for the factory DC board in many Kato, Athearn Genesis, Stewart and similar HO locomotives. No harness to route. 8 FX7 function outputs at 300mA - enough for headlights, ditch lights, number boards, cab light and class lights, with prototypical effects on each. 1.0 amp continuous, 2.0 amps peak - ample for single-motor HO diesels. Series 7 platform with back-EMF speed stabilisation for steady low-speed control. Standard NMRA DCC - runs and programs on any DCC system, not just Digitrax. More Information Brand Digitrax Item Number DH187A0 Product Type DCC Mobile Decoder (Drop-In Board) Scale HO Motor Current 1.0 A continuous / 2.0 A peak Function Outputs 8 x FX7, 300 mA Connection Direct board replacement Series Digitrax Series 7 Sound No - motor and function decoder only Condition New FAQ How do I know it will fit my locomotive?Drop-in boards are shape-specific. Pull the shell and compare the factory board footprint, mounting clips and light positions against the DH187A0. It is the usual fit for many Kato, Athearn Genesis and Stewart HO diesels, but check yours before ordering - if it does not match, a wired decoder such as the DH127D is the fallback. Why choose a drop-in board over a plug-in decoder?No harness and no wire to hide, and the lighting stays where the manufacturer put it. On models where the light board also carries the motor contacts, a drop-in is usually the cleanest install you can do. What can I do with eight function outputs?Headlight and rear headlight, ditch lights that alternate with the horn, number boards, cab light, class lights - each output can be assigned its own effect and dimming via CV settings. Does it have sound?No. This is a motor and function decoder. For sound in HO, look at a Digitrax SDXH series decoder or a SoundTraxx unit, plus a speaker.

The Digitrax UP6Z does two jobs at once. It is a LocoNet universal panel with six jacks for plugging throttles and daisy-chaining LocoNet around the layout, and it is a 3 amp voltage reducer that drops track voltage by 4 or 6 volts. Z scale motors were never built for full HO track voltage, and that reduction is what keeps them running at sane speeds and sane temperatures on Digitrax equipment. More LocoNet gear? Browse our DCC Accessories, DCC Wiring, and the full Digitrax range. Features Reduces track voltage by 4 or 6 volts at 3 amps - selectable, for safer Z scale running on a Digitrax system. Six LocoNet jacks for throttles and for daisy-chaining LocoNet onwards around the layout. Usable in any scale as a universal panel - the voltage reduction is what makes it specifically useful for Z. Fascia mounted, so throttles plug in where the operator is standing. Uses standard 6-conductor LocoNet cable with RJ12 connectors. More Information Brand Digitrax Item Number UP6Z Product Type LocoNet Universal Panel with Voltage Reducer Primary Scale Z Voltage Reduction 4 V or 6 V, selectable Current Rating 3 A LocoNet Jacks 6 Cable Type 6-conductor with RJ12 connectors Condition New FAQ Why does Z scale need reduced voltage?A standard DCC booster puts out track voltage suited to HO and larger. Z scale motors run hot and far too fast on that. Dropping 4 to 6 volts brings the top speed and the motor temperature back to something sensible. Do I choose 4 V or 6 V?It depends on your booster output and how your locomotives behave. Start with the smaller reduction, check top speed and motor temperature, and increase it if the trains still run too fast. Can I use it on an HO layout?Yes, as a plain universal panel with six LocoNet jacks. The voltage reduction is the feature you would not need there - if HO is all you run, a UP7 is the simpler choice. How many amps will it pass?Three amps, which is ample for a Z scale layout - Z locomotives draw a fraction of what larger scales pull.

The Digitrax SE74 is the signal and turnout decoder that ties a working signal system to your LocoNet. It drives signal masts, throws four turnouts, reads eight input lines for sensors and local push buttons, and stores eight routes of eight entries each - which means interlockings and crossovers can be set from a single command instead of one turnout at a time. Signalling your layout? Browse our DCC Accessories, DCC Wiring, and the full Digitrax range. Features Fully connectorized installation - signal driver cables and turnout leads plug in, so a signal bay can be built on the bench and dropped under the layout. Four turnout outputs, configurable for solenoid machines (Peco, Atlas, Kato) or slow-motion machines such as the Tortoise. 8 input lines for block detectors, sensors and local control buttons at the fascia. 8 system routes with 8 entries each - throw a whole crossover or interlocking from one command. Optional DCC 9-aspect control mode, including Lunar aspects, for prototypical signalling. Setup via option switches or LocoNet programming, with Series 7 style configuration from a DT602 throttle. More Information Brand Digitrax Item Number SE74 Product Type DCC Signal and Turnout Decoder Scale All scales Turnout Outputs 4 - solenoid or slow-motion Input Lines 8 Routes 8 routes x 8 entries Signal Aspects Up to 9-aspect DCC mode including Lunar Connection LocoNet, connectorized signal driver cables Condition New FAQ What else do I need to get signals running?The SE74 plus signal masts and a way to carry the connections to them. Most installs use a Signal Driver Cable Kit (SDCK) for the ribbon cable and sockets, plus mast bases and mounting hardware. You also need occupancy detection - the SE74 displays aspects, it does not detect trains on its own. Can it drive slow-motion turnout machines?Yes. The four turnout outputs are configurable for either solenoid machines such as Peco, Atlas and Kato, or stall-motor machines such as the Tortoise. What are routes and why do they matter?A route sets several turnouts at once from a single command. With eight routes of eight entries you can line an entire crossover or interlocking with one button press instead of throwing each point individually. Do I need a Digitrax command station?Yes for full configuration - the SE74 is a LocoNet device and is set up over LocoNet, with the most convenient programming from a DT602 throttle.

The Digitrax DS52 is a two-output stationary decoder that will drive either kind of turnout machine - slow-motion stall motors such as the Tortoise and Switchmaster, or solenoid machines such as Peco, Atlas Snap Switches and Kato Unitrack. The capacitive discharge circuit gives solenoids the hard kick they need to throw reliably, and everything lands on screw terminals, so a board goes in with a screwdriver and no soldering. Wiring a layout? Browse our DCC Accessories, DCC Wiring, and the full Digitrax range. Features Drives two turnout machines of either type - two slow-motion stall motors, or two solenoid machines, whichever your layout uses. Capacitive discharge for solenoids gives twin-coil and bi-polar machines a proper snap, including Kato Unitrack, AristoCraft and LGB two-wire types. Screw terminals throughout - wire it in with a screwdriver, no soldering under the layout. Addresses set individually or sequentially, so the two outputs can sit anywhere in your numbering scheme or as a consecutive pair. Works in all scales on track power up to 22V. Standard DCC accessory decoder - works with any NMRA DCC system, not just Digitrax. More Information Brand Digitrax Item Number DS52 Product Type DCC Stationary (Accessory) Decoder Scale All scales Outputs 2 turnouts Machine Types Slow-motion stall motor, or 2-wire bi-polar and 3-wire solenoid Solenoid Drive Capacitive discharge Addressing Individual or sequential Connections Screw terminals Max Track Voltage 22 V Condition New FAQ Will it drive Tortoise machines?Yes. The DS52 handles two slow-motion stall-motor machines such as the Tortoise by Circuitron or the Switchmaster, as well as solenoid types. You select the mode when you set it up. Will it throw Kato Unitrack turnouts?Yes. Kato Unitrack uses a two-wire bi-polar solenoid, which the DS52 drives through its capacitive discharge circuit - the same circuit that handles three-wire Peco and Atlas Snap Switch machines. Can I mix machine types on one decoder?The two outputs share a configuration, so plan on a DS52 per pair of like machines rather than mixing a Tortoise and a snap switch on the same board. Do I need a Digitrax system?No. It is a standard NMRA DCC accessory decoder and will take turnout commands from any DCC system.

The Digitrax SNABC is a complete turnout signalling kit in N scale. A turnout takes three signals to do properly - a dual-head mast facing the points that shows both routes, plus single-head masts covering each leg beyond - and the kit includes all three along with the mounting board, plugs and hardware. Current-limiting resistors are already fitted, which matters more in N scale where the LEDs are small and unforgiving. Signalling your layout? Browse our DCC Accessories, DCC Wiring, and the full Digitrax range. What's Included Item Qty Dual Head A Signal 1 Single Head B Signal 1 Single Head C Signal 1 SMP1 signal mast plug 3 Spacers 6 Screws 6 Features Everything for one N scale turnout signal plant - three signals, mast plugs, spacers and screws. Dual-head A signal for the straight and diverging routes at the points, plus B and C single heads for each leg. Plug and play 10-pin connectors so signals lift out during ballasting and scenery work - worth a lot on an N scale layout where everything is close together. Current-setting resistors built into the board - nothing to calculate, nothing to solder. Pads are provided to attach any signal head to the mast base if you want to mix in other manufacturers. Intended for use with the Digitrax SE8C signal decoder. More Information Brand Digitrax Item Number SNABC Product Type Signal Kit Scale N Configuration Turnout - A, B and C masts Signal Heads 1 dual head, 2 single head Connector 10-pin plug and play Resistors Built into the mounting board Use With Digitrax SE8C signal decoder Condition New FAQ What is the difference between this and a mainline kit?A turnout needs three signals: a dual-head mast protecting the points and showing both routes, plus single-head masts for each leg beyond. A mainline kit only covers plain double track. Is this the N scale version of the SHABC?Yes. Same configuration and the same contents, with signal heads scaled for N. Do I need anything else to make the signals work?Yes - a signal decoder to drive the aspects (the SE8C is the intended partner), cabling to reach the masts such as the SDCK kit, and some form of block occupancy detection. Do I need to add resistors?No. Current-setting resistors are already on the mounting board, so there is no resistor maths and no risk of over-driving an LED.

The Digitrax SP53188B is the big one - a 53 x 18 x 14mm 8 ohm speaker in a sealed enclosure, with roughly four times the cone area of a compact box speaker. Where there is room for it, in an HO long hood, a large tender, or anything O and G scale, it is the difference between a locomotive you can hear and one you can feel. Looking for more DCC sound gear? Browse our DCC Speakers, DCC Decoders, and DCC Accessories. Features 53 x 18 x 14mm enclosure - the largest of the Digitrax box speakers, with the cone area and internal volume to produce genuine low end. Sealed enclosure included. No scratch-building a baffle from styrene; the acoustic work is already done. 8 ohm, 1/2 watt - matches the speaker output on most DCC sound decoders. Interface wires pre-attached for soldering straight to the decoder speaker pads. Measure first: at just over 2 in. long and more than half an inch deep, this needs a long hood, a tender, or an O scale frame. For tighter installs use the 26.5 x 15.5 x 9mm SP26158B. More Information Brand Digitrax Item Number SP53188B Product Type DCC Sound Decoder Speaker with Enclosure Speaker Shape Rectangular box Dimensions 53 mm x 18 mm x 14 mm Impedance 8 Ohm Power 1/2 Watt Enclosure Included, sealed Connection Bare interface wires (no plug) Recommended Scale HO, O, G Condition New FAQ Will this fit in an HO locomotive?In a diesel long hood or a decent-sized steam tender, usually yes - it needs about 2-1/8 in. of length, 3/4 in. of width and 9/16 in. of depth. In a short switcher or a boiler, it will not. Measure before ordering, or step down to the SP26158B. Is it really that much louder than a compact speaker?Yes. Cone area and enclosure volume are what produce bass and output, and this has far more of both. It is the single biggest upgrade you can make to a sound install that has room for it. Do I need 8 ohm or 32 ohm?Check your decoder manual. Most DCC sound decoders drive 8 ohms, which is this speaker. If yours specifies 32 ohms, order the Digitrax SP531832B - the same speaker and box in a 32 ohm version. Does it come with a plug?No, it has bare interface wires for soldering to the decoder. If you need a plug-in speaker, the Digitrax SP26158BC has a 2-pin plug, though it is the smaller box.

The Digitrax SP26158BC is a 26.5 x 15.5 x 9mm 8 ohm speaker supplied in a sealed enclosure and terminated in a 2-pin plug. If your decoder or locomotive motherboard has a matching speaker socket, this is the no-solder option: unplug the old speaker, plug this one in, and the install is done. The sealed box does the acoustic work that a bare cone cannot. Looking for more DCC sound gear? Browse our DCC Speakers, DCC Decoders, and DCC Accessories. Features 2-pin plug terminated - drops straight onto compatible Digitrax motherboards and decoders with a speaker socket. No soldering at the speaker end. Sealed enclosure included. Nothing to scratch-build; the box stops the rear wave cancelling the front wave, which is where volume and low end come from. 26.5 x 15.5 x 9mm footprint fits HO diesel hoods, steam tenders and O scale frames where a 28mm round speaker will not clear. 8 ohm, 1/2 watt - matches the speaker output on most DCC sound decoders. Same speaker and box as the Digitrax SP26158B; the only difference is the plug instead of bare wires.

The BC ends in a 2-pin plug for decoders and motherboards with a speaker socket. The B has bare interface wires you solder to the decoder pads. Speaker, enclosure and specs are otherwise identical. Will the plug fit my decoder?It mates with the 2-pin speaker socket used on compatible Digitrax locomotive motherboards. If your decoder has solder pads rather than a socket, order the SP26158B with bare wires, or cut the plug off and solder the leads. Do I still need to build a baffle?No. The enclosure is included and already sealed. Mount it where the opening is not blocked by the frame or a weight and you are finished. Will it work with my sound decoder?Any DCC sound decoder rated for an 8 ohm speaker output. If your decoder manual specifies 32 ohms, use a 32 ohm speaker such as the Digitrax SP531832B instead.

The Digitrax SP531832B is the largest Digitrax box speaker in its 32 ohm version - a 53 x 18 x 14mm driver already mounted in a sealed enclosure, for sound decoders whose amplifier expects a 32 ohm load. Where you have room for it, in an HO long hood, a large tender, or an O or G scale frame, the cone area and box volume give you low end that compact speakers simply cannot produce. Looking for more DCC sound gear? Browse our DCC Speakers, DCC Decoders, and DCC Accessories. Features 32 ohm impedance for decoders that specify a 32 ohm speaker. Matching the decoder spec is what keeps the sound clean and the amplifier safe. 53 x 18 x 14mm enclosure - the biggest of the Digitrax box speakers, with the internal volume to produce genuine bass. Sealed enclosure included. No scratch-building a baffle; the acoustic work is already done. 1/2 watt rating with interface wires pre-attached for soldering straight to the decoder speaker pads.

Use this 32 ohm version only where the decoder calls for 32 ohms. If it calls for 8 ohms, order the Digitrax SP53188B - the identical speaker and box in 8 ohm. What happens if I fit the wrong impedance?Too high and the sound is quiet and thin. Too low and the decoder amplifier draws more current than it is rated for, which can overheat or damage it. Always match the decoder spec. Will it fit in an HO locomotive?In a diesel long hood or a good-sized steam tender, usually yes - allow about 2-1/8 in. length, 3/4 in. width and 9/16 in. depth. In a switcher or a boiler it will not. Measure before ordering. Do I still need to build a baffle?No. The enclosure is included and sealed. Just mount it where the opening is not blocked by the frame or a weight.

The Digitrax SP13138 is a 13mm round 8 ohm speaker for the tightest sound installs. At just over half an inch across it drops into N scale shells, tenders and small HO hoods where a 28mm speaker will never fit, and it ships with interface wires already attached so there is nothing to solder at the speaker end. Looking for more DCC sound gear? Browse our DCC Speakers, DCC Decoders, and DCC Accessories. Features 13mm round footprint fits N scale bodies, tenders and cramped HO installs where larger speakers will not clear the frame. 8 ohm impedance matches the speaker output on most DCC sound decoders, including the Digitrax SDN144 and Series 7 families. Interface wires pre-attached - strip, tin and solder to the decoder pads, no work needed at the speaker. Baffle or enclosure strongly recommended. Mounted in a sealed box the same speaker gains noticeable volume and low end; run bare and it sounds thin. Works with any DCC sound decoder rated for an 8 ohm load, Digitrax or otherwise. More Information Brand Digitrax Item Number SP13138 Product Type DCC Sound Decoder Speaker Speaker Shape Round Diameter 13 mm Impedance 8 Ohm Connection Bare interface wires (no plug) Enclosure Not included - baffle recommended Recommended Scale N, HO Condition New FAQ Will this speaker work with my sound decoder?Yes, as long as the decoder drives an 8 ohm load. Check your decoder manual for the rated speaker impedance - a decoder that specifies 32 ohms needs a 32 ohm speaker instead, such as the Digitrax SP282832. Do I really need a baffle or enclosure?It makes a large difference. A bare speaker cone lets front and back waves cancel each other, which kills the bass. A sealed box - even one you fold from sheet styrene - will noticeably improve volume and tone. Can I wire two of these to one decoder?Two 8 ohm speakers in series give 16 ohms, which is safe for most decoders. Wiring them in parallel drops the load to 4 ohms and can damage the decoder, so check the manual before doubling up. Does it come with a plug?No. The SP13138 has bare interface wires. If you want a speaker that plugs straight into a compatible motherboard, look at the Digitrax SP26158BC with its 2-pin plug.
