Train Tech SC3 DCC signal controller - for original style Dapol dual semaphore signals

The SC3 controls one or two Dapol N or OO gauge motorised semaphore signals by DCC. Please note this is for the original model of signals using two wire connections, for newer models please use SC4, available separately.

Each signal can be given a separate DCC address with their position controlled by the SC3. The signals connect directly using their wires and no modification or power supply is required.
