Model Railroad LED traffic light controller module for O, HO, N gauge

This is a compact PCB to control 1, 2, 3 or 4 LED traffic lights in any railway model. This version has current limiting built in for LEDs. If filament lamps such as grain of wheat bulbs are used, we have an alternative version. The PCB is just 1.5" x 1.6" with four fixing holes for convenient mounting. All connections use spring terminals for a reliable connection without the need for tools. The circuit requires a supply voltage of 8V to 16V to drive the LEDs.

Full installation and configuaration instructions are supplied and we offer email support for technical queries. This circuit uses commercial grade micro-controllers for reliable operation and stable timings, regardless of supply voltage or temperature. Select UK or US / European traffic light sequence using jumper link on the board. UK light sequence Red Red / Amber Green Amber Red US / European sequence Red Green Yellow Red.

When in US operation mode, a separate switch or voltage input sets an off-peak mode with one way flashing yellow and the other flashing red. Removing the input will restore normal operation.
