American Fibertek RT82 Sixteen Channel Contact Closure System, Multimode, Rack Card Transmitter

The American Fibertek RT82 is the rack card transmitter component of the 81 series which multiplexes 16 channels of dry latching contact closure on two multimode fibers. 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 are 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.
