American Fibertek MR81SL Eight Channel Contact Closure System, Single Mode, Module Receiver

The American Fibertek MR81SL is a receiver component module of the 81SL series which multiplexes 8 channels of dry latching contact closure on one singlemode 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. Equipment may be ordered as stand alone modules or rack cards that are mounted in the SR-20D/2 or SR-20R/1 AFI Card Cages.
