The S.I.Tech Model 2811 TR transmits a 10 KHz optical square wave over optic fiber when power is applied and control input shorted. The 2812 receiver detects this optical square wave and turns ON a 4PDT relay. If the fiber cable is removed, broken, or the remote transmitter or local receiver loses power, the relay in the local receiver will turn OFF. The 4 sets of Form C (4PDT) relay contacts are provided on the rear panel via screw terminal blocks. The power input (+12 VDC or +24VDC is also via screw terminals. The fiber optic input/output is provided on the rear panel via ST recepta 905/906 compatible SMA receptacles are available as an option. The front panel contains 2 indicator LEDs, a power ON indicator and a CARRIER (10 KHz detected) indicator.
