Comnet FDC8NLRM1 | 8-Channel Contact Closure Non-Latching Receiver, Multimode, 1 Fiber Required, 1 Rack Slot

The ComNet FDC8NLR 8-Channel Contact ClosureReceiver unit provides up to eight independent normallyopen(NO) dry contact closures over one multimode orsingle-mode optical fiber, when used in conjunction withthe companion ComNet model FDC8 Transmitter un it.Microprocessor-based logic in the FDC8 transmitterdetects a customer-furnished switch or contact closure,and encodes the closure into robust data packets thatare mapped and transmitted to the FDC8NLR Receiver.Packets received with excessive bit erro rs will notresult in random changes in the receiver relay contactresting or actuated states, making this system ideal formission-critical remote switching applications.

Solid-statenon-latching relays are utilized for the highest level oflong-term syste m reliability and trouble-free operation;electromechanical relay switching is not employed.

Therelay contacts automatically default to a normally-openstate in the event of a loss of prime operating power or aloss of the received optical signal.

These r eceiver modulesincorporate status indicating LEDs for rapidly providing alocal indication of each contact closure channel, opticallink continuity, and operating power.

Packaged in theexclusive ComNet ComFit housing, these units may beeither shelf or rack-mounted, or may be DIN-rail mountedby the addition of ComNet model DINBKT1 Adaptor PlateKit.

Industrially hardened and rated for operation from-40 to +75 degrees C, the FDC8NLR may be deployedin virtually any unconditioned out-of-plant or trackside/ roadside environment, and voltage transient protectionis provided across the operating voltage input and relaycontact output rails.

Plug-and-play design ensures easeof installation and operation, and no optical or electricaladjustments are ever require d.
