Digitrax SNABC | Turnout Signaling Kit | N Scale

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.

• 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.

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.
