American Fibertek MRX81BSL 4 Channel Bi-Directional Contact Closure System, Module Receiver, Single Mode

The American Fibertek 81B-SL Series multiplexes 8 total channels (4 contact in and 4 contact out) of dry latching contact closure on one singlemode fiber. A user-selectable feature allows the contact status to be maintained unchanged through power-cycle and loss-of-opticalpower. A reset button is available to clear all contact status to the default state. A set of 8 LEDs on the transmitter and the receiver units indicates the channel(s) status. These systems require no field adjustments at installation or additional maintenance thereafter. Diagnostic indicators provide a quick visual indication of system status. The Afinety intelligent remote monitoring system is available on the Rack Card product, please consult factory.

Equipment may be ordered as stand alone modules or rack cards that are mounted in the American Fibertek Card Cages: SR-20/2 or SR- 20R/1.
