American Fibertek RT-81 8 Channels Contact Closure System with Power Fail Safe

The American Fibertek 81 Series multiplexes 8 channels 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. 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.
