American Fibertek MRX-81B 4 Channel Module Receiver Bi-Directional Contact Closure System

The American Fibertek 81B Series multiplexes 8 total channels (4 in each direction) of dry latching contact closure on one multimode 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.
