Programmable LED Traffic Lights Controller with Fading Easy to wire and operate Realistic operation with fading between aspects to simulate filament lamps Can connect to a wide variety of supply voltages for easy powering UK and Continental switching sequences catered for No external resistors required as they are built in to the module Timings and other settings can be adjusted if required The BLOCKsignalling TLC2A Traffic Light Controller has been designed for railway modellers to make it very quick and easy to add traffic light signals to their layouts. The unit can connect to AC, DC and DCC power supplies to make powering it as flexible as possible. Whichever voltage you connect, the module automatically reduces the supply voltage to provide a stable feed to the traffic lights. To simplify wiring, resistors are built-in, so it is not necessary to connect in or solder additional resistors to the traffic lights (any already installed can remain). The module is pre-programmed to replicate the standard UK sequence, but it is a simple matter to change this to follow a continental sequence to suit the model. This model (TLC2A) is designed for traffic lights which have a common-anode connection, the positive (anodes) of each of the leds are connected together at each light. If you have traffic lights with common-cathode connections where the negative (cathodes) of the leds are wired together, then the complimentary BLOCKsignalling TLC1A should be used.
