SIGM 20 Signal Controller - $70

Brand new CML Electronics SIGM 20 Signal Controller for Loconet DCC

The SIGM20 is an automatic controller for eight signals. It sets the signal state automatically according to the state of the trackwork (e.g. points), other signals and block occupancy detectors. It does this automatically, without any other computers involved: so no PC is required to operate the railway. The board can control simple blocks, simple and complex junctions ....automatically.

Signals are controlled automatically as trains move around the railway. Signals can be programmed so that for example:

- If the track ahead is occupied by another train, the signal will go red;
- If a point is set against the track, so that it would not be safe to proceed, the signal goes red;
- That can be extended to set the signal through complex junctions;
- The logic for 3 and 4 aspect signals is followed: if the next signal is red, this signal will go amber and so on.
