The American Fibertek RRX-81B-SL is the rack card receiver component of the 81B-SL series which multiplexes 8 total channels (4 in each direction) of dry latching contact closure on one single mode fiber. A user selectable feature allows the contact status to be maintained unchanged or reset through power-cycle and loss-of-optical-power. A reset button is available to clear all contact status to the default state. Individual channel LEDs on the transmitter and the receiver units indicate the channel status.

These systems require no field adjustments at installation or additional maintenance thereafter. Diagnostic indicators provide a quick visual indication of system status.

Rack cards can be mounted in the SR-20D/2 or SR-20R/1 AFI Card Cages. The Afinety intelligent remote monitoring system is available on the Rack Card product, please consult the factory.
