Powers and controls two New Dapol Servo type Semaphore Signals from DCC & Track Sensors.
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.
 
Features
Connect and independently control one or two signals
One-Touch DCC™ setting up - NO programming of CV codes etc!
Simple 2 wire connection to either DCC track or controller - no separate power needed
Signals connect direct to the module with fitted screw terminals - no resistors etc required
Signals can work independently or mirror another - ideal for home and distant signals!
Works with most DCC controllers with accessory control or computer controlled layouts
Pack contains Signal controller and instructions
Substitute for Dapol 4A-001-002
 
Note: it is very important to only connect Dapol Servo Signals control wires to 'volt free' controllers otherwise permanent damage may result. The SC4 and SC400 have been designed specifically to power and control the new Dapol Servo type OO bracket and O gauge semaphore signals and feature safe optically isolated volt free contacts and a regulated protected power output.
