American Fibertek MR88 8 Channel Supervised External Contact Closure System, Multimode, Module Receiver

The American Fibertek MR88 is a receiver component module for the 88 series which multiplexes 8 channels of supervised input dry contact closure on one multimode fiber. A set of 8 LEDs on the transmitter and the receiver units indicates the channel(s) status.

The contact input supervision will detect an open connection and a shorted connection as an alarm. The alarm condition is removed only when the contact input voltage falls within a predetermined range.

Failsafe operation is provided such that, if the optical power is loss or the transmitter or receiver DC power is loss, the normally open contact outputs will go to the alarm states (open).
