American Fibertek MR88SL 8 Channel Supervised External Contact Closure System, Single Mode, Module Receiver

The American Fibertek 88SL Series multiplexes 8 channels of supervised input dry contact closure on one singlemode 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).

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 Cage: SR-20/2Sixteen Channel Contact Closure System
