Digital On-Off Fiber Optic Link

S.I. Tech Model 2813 Digital On-Off Fiber Optic Link

The S.I.Tech Model 2813 ON-OFF fiber optic link contains a fiber optic transmitter that generates a 10 KHz optical square wave. The 2813 fiber optic receiver detects a 10 KHz optical square wave and turns ON a relay. The relay provides 4 sets or Form C (4PDT) relay contacts available on the rear panel via screw terminals. The power input (+24 VDC or +12 VDC) is also via screw terminals.

When power is applied to the Model 2813, the receiver becomes active. If the receiver detects the optic signal it will operate the relay. The transmitter is turned on by an external switch across the input screw terminals. If the fiber cable is broken or removed, the relay will release. The fiber optic input/output is provided on the rear panel via ST receptacles,
905/906 compatible SMA receptacles are available as an option.

The front panel contains 2 indicator LEDs, a green power ON indicator and a green CARRIER (10 KHz detected) indicator.
