Dapol are pleased to announce the SC3 DCC controller for its range of OO and N gauge Semaphore signals which enable standard signals to be quickly and easily connected to a standard DCC layout and controlled using almost any controller or computer system which can control DCC accessories. Each controller can independently control 1 or 2 standard Dapol Semaphore signals which wire straight into the module and 2 wires connect direct to the nearest track or DCC bus – no extra power supply or wiring is needed.
