The Model Train Technology™ DPDT Relay Board™ provides a simple way to connect the MTT Precision Sensor to trigger a DPDT (Double-Pole, Double Throw) relay.
You can use this setup automatically turn Motorized turnouts or to show a bi-color LED on a panel in synchronization with any action that is triggered by our Precision Detector.
This relay circuit is purpose build for our detector and may not work with other sensor systems unless they have an ACTIVE LOW signal.
The relay contacts are rated to 1A.
Use the same 12VDC power source to power the Precision Detector and the DPDT Relay Board. You may connect the Precision Detector yellow signal wires to BOTH this relay board AND any Signal Controller in our product lineup.
