ON-OFF Fiber Optic Link Model 2813

Model 2813
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 3 sets or Form C (3PDT) relay contacts available on
the rear panel via screw terminals. The power input (+24 VDC or +12
VDC) is also via screw terminals.
S.I.Tech Bit-Driver®
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.
