DCC Decoders

Sound and non-sound DCC decoders from SoundTraxx, ESU, Digitrax and Train Control Systems. To pick the right one, match three things to your locomotive: the connection (hardwire, 8-pin, 21-pin or Next18 plug), the motor current it needs, and for sound decoders the prime mover or steam profile. Each product page lists its connection, current rating and sound set. Not sure what fits? Ask us before you order.

    1 In Stock In Store

    While LokPilot 5 decoders can undoubtedly meet all imaginable requirements of even the most demanding experts, many model railway eras are looking for a robust, high-quality DCC decoder for your standard requirements, which should also be affordable. The LokPilot 5 Basic was developed with the aim of offering a modern decoder with a reasonable range of functions at a reasonable price. The LokPilot 5 Basic comes in two versions: In addition to a version with an 8-pin NEM interface, a version with 21MTC interface is also available. This makes the LokPilot 5 Basic particularly suitable for use in track H0 vehicles. Modes The LokPilot 5 Basic is a "pure-bred" DCC decoder. 14 to 128 driving steps are as self-evident as 2- and 4-digit addresses. Up to 20 functions can be triggered. Thanks to RailComPlus®, the decoders log in fully automatically to a suitable digital center. It masters all DCC programming modes and thanks to RailCom® the CV values can be read out on the main track with suitable control panels. Auxiliary registers exist for control panels that can only program the CVs from 1-255. The LokPilot 5 Basic Decoder detects the Märklin® brake distances as well as the Lenz® ABC system. Braking with DCC brake blocks or dc voltage is also possible.The LokPilot 5 Basic Decoder can be used on analog DC webs. The maximum speed can be set separately.The decoder switches "on-the-fly" fully automatically between operating modes. Most of the time, nothing needs to be adjusted. Functions The LokPilot 5 Basic has 4 reinforced function outputs in each version. In the 21MTC interface, there are 8 logic-level outputs at the interface, two of which are also suitable for controlling servos. All important lighting functions are available. The brightness of each output can be set separately. Motor The motor control of the LokPilot 5 Basic delivers up to 0.9A continuous current. A variable PWM clock frequency from 10kHz to 50kHz ensures super-quiet operation, especially for bell anchor motors – The typical "hum" is a thing of the past. The load control can be adapted to difficult cases with up to 10 CVs. The unique "Autotune" function allows the decoder to be automatically measured against the motor. Operational reliability On request, a PowerPack can be connected to the LokPilot 5 Basic to bridge dirty rail cuts. Protection Of course, all function outputs as well as the motor output are protected against overload. We want you to enjoy your decoder for as long as possible.

    Digitrax Digitrax DH187A0 | Series 7 Mobile Decoder | HO Scale

    1 In Stock In Store

    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 SoundTraxx 885607 is a BLU-2200 Blunami digital sound decoder with the ALCO sound set. Blunami is a Tsunami2 with a Bluetooth radio added, so it runs three ways: as a normal DCC decoder on any NMRA-compliant system, on plain DC, or in wireless mode straight from your phone or tablet. Wireless mode needs no command station and no programming track — an old DC power pack and the free Blunami app are enough, and CVs can be read and changed over Bluetooth while the locomotive is running. The app is free for iOS and Android. This version is the universal-style Blunami that fits most HO diesels, suited to HO and small S scale. Features 9 ALCO prime movers: ALCO 539 Turbo, ALCO 539 Non-Turbo, ALCO 244 Turbo, ALCO 251A i6, ALCO 251C v12, ALCO 251C v12 Super Charged, ALCO 251C v12 Century Series, ALCO 251C v16, ALCO 251C v16 Super Charged Over 40 air horns and 13 bells, plus air compressors, couplers and dynamos Bluetooth control from the free Blunami app (iOS and Android) — over 300 settings without editing a single CV by hand Dynamic Digital Exhaust (DDE) automatically matches exhaust volume and RPM to the load on the motor, and the app calibrates it for you Three braking types: independent, train and dynamic braking Hyperdrive2 motor control for smooth, creep-speed switching Over 20 Hyperlight lighting effects across 6 function outputs 16 polyphonic sound channels on a 32-bit processor, with a 7-band equalizer and adjustable reverb CurrentKeeper ready — works with the SoundTraxx 810140 CurrentKeeper More Information Item Number: SoundTraxx 885607 Model: BLU-2200 Blunami Sound Set: ALCO Diesel Scale: HO and small S scale Decoder Size: 35 x 18 x 6mm Connection: NMRA 9-pin JST harness to hardwire Max.

    The SoundTraxx 885030 is a TSU-N18 Tsunami2 digital sound decoder with the EMD-2 sound set. Tsunami2 combines a 16-bit sound system, Hyperdrive2 motor control, Hyperlight lighting effects and a full NMRA-compliant DCC decoder on one board, driven by a 32-bit processor with 16 polyphonic sound channels. This version is the Next18 decoder for N and small HO models, rated 1A and suited to N and small HO models with a Next18 socket. Dynamic Digital Exhaust reads the load on the motor and notches the engine up and down on its own, so the locomotive sounds like it is working for its train. Features 8 EMD-2 prime movers: EMD 567 12-cylinder (no transition), EMD 567C 16-cylinder non-turbo, EMD 645E 12-cylinder non-turbo, EMD 645E 12-cylinder turbo, EMD 645F 16-cylinder turbo, EMD 645E 20-cylinder turbo, EMD 710G 12-cylinder, EMD 710G 16-cylinder Over 40 air horns and 13 bells, plus air compressors, couplers and dynamos Dynamic Digital Exhaust (DDE) matches exhaust volume and RPM to the load on the motor automatically Three braking types: independent, train and dynamic braking Hyperdrive2 motor control for smooth, creep-speed switching Over 20 Hyperlight lighting effects across 6 function outputs 16 polyphonic sound channels on a 32-bit processor, with a 7-band equalizer and adjustable reverb CurrentKeeper ready — works with the SoundTraxx 810140 CurrentKeeper More Information Item Number: SoundTraxx 885030 Model: TSU-N18 Tsunami2 Sound Set: EMD-2 Diesel Scale: N and small HO models with a Next18 socket Decoder Size: 25 x 9.5 x 4.1mm Connection: Next18 (N18) socket Max.

FAQ Will this fit my locomotive?It measures 25 x 9.5 x 4.1mm and connects by next18 (n18) socket.

The plain EMD set covers the more common 567/645/710 variants. Does it run on DC?Yes. Tsunami2 runs on a standard DC power pack as well as DCC, though sound and lighting options are limited on DC. Full function control needs a DCC system.
