Electronics For Your Model Railroad

Our products are fully compatable with all signals, scales and control systems (DC or DCC), and operate independently of these systems. They include detection and provide prototypical operation independent of track power. No soldering necessay and donot disrupt existing layouts.

The FlashMaster

Provides prototypical grade crossing flasher control. The basic unit is configured for one track bi-directional operation, it can be expanded to two track operation with the addition of an Optical Sensor Cable. Beyond two tracks an additional control card is required. The unit can drive up to 8 pairs of LEDs and requires 7-18 volts AC or DC 300ma.

#8003    FlashMaster        $59.99

#8004    Optical Sensor Cable        $24.99

The ServoMaster

Provides activation for Crossing Gates & 3 Position Semaphores. For Crossing Gates 4 optical sensors will allow single track bi-directional operation, or dual track uni-directional operation. Expansion kits will allow up to 3 additional bi-directional tracks. The unit also controls the crossing lights for common Anode LEDs. An output is provided to add a bell sound module (not provided). The ServoMaster requires 9-16 volts, AC or DC rated for at least 500ma.
