SAS2 BLOCK SIGNALLING IR DC SHUTTLE INFRA~RED DETECTION.
Shuttle Model Train Controller with Infra-Red Detection
Automatically operates a train backwards and forwards along a single line.
Train detection using Infra-red sensors (no track cutting required).
Waiting time at either end is adjustable or can be set to random.
Optional Route Indication leds can be connected to show train waiting at either end, or in transit up or down the line.
Optional 2-aspect signals can be connected, and will switch to green three seconds before train departs, and back to red two seconds later.
The BLOCKsignalling Simple Automatic Shuttle SAS2-IR is designed to automate a DC model train running backwards and forwards along a single length of track.
At each end of the track, an Infra-Red sensor is fixed below the track to detect the train which stops when the module switches off the track power.
The train waits until the track current is switched back on in reverse and the train then
automatically starts travelling in the reverse direction.
This action is repeated at each end of the line.
The module is fully programmable, and can be to selected to fixed or random waiting time at one or both ends of the line,
and can also be programmed for the maximum waiting time.
Each of the relays are rated at 10A for long life (traction current is typically 0.5A to 1A).
Power Supply
The controller is designed for use with a DC power supply of between 8V and 25V, or an AC power supply of between 8V and 16V.
Where there is a choice, the recommended power supply is 12V DC.
