Manufacturer description

The SC400 is specifically designed to power and control the new Dapol Servo controlled signals which have three wire inputs for each signal. An SC400 can control one, two or a twin head (e.g. Bracket) servo signal and each can easily be assigned any DCC accessory address & run the two arms independently or together in Home-Distant pairs. It also incorporates a regulated power supply to provide a stable safe voltage for the signals from the standard DCC track supply. It has inputs for Track Sensors allowing the Semaphore Signals to operate automatically when trains are sensed on the track!

The SC400 is also Layout Link compatable and may be linked to Mimic Switches and Mimic Lights so that Dapol Semaphore signals can be controlled and monitored from a Mimic panel. The Track sensor and Mimic switch features can be used on analogue DC as well as digital DCC layouts.

Catalogue listing

Train Tech Dual Dapol Servo Signal Control Plus Automation (part number TTSC400) is a controller designed to power and manage Dapol servo‑controlled railway signals that use three‑wire inputs.

The SC400 can operate a single signal, a pair of signals or a twin‑head (bracket) arrangement. Each signal may be assigned any DCC accessory address and the two arms can be driven independently or together as a Home‑Distant pair. The unit includes a regulated power supply that derives a stable, safe voltage for the signals from the standard DCC track feed, and it provides inputs for track sensors so that semaphore signals can be set automatically when a train is detected on the track.

The controller is compatible with the Layout Link system and can be linked to Mimic Switches and Mimic Lights, allowing Dapol semaphore signals to be controlled and monitored from a Mimic panel. The track‑sensor and Mimic‑switch functions operate on both analogue DC and digital DCC layouts.
