Description

The ComNet(TM) FDC8NLR 8-Channel Contact Closure Receiver unit provides up to eight independent normally open (NO) dry contact closures over one multimode or single-mode optical fiber, when used in conjunction with the companion ComNet model FDC8 Transmitter unit. Microprocessor-based logic in the FDC8 transmitter detects a customer-furnished switch or contact closure, and encodes the closure into robust data packets that are mapped and transmitted to the FDC8NLR Receiver. Packets received with excessive bit errors will not result in random changes in the receiver relay contact resting or actuated states, making this system ideal for mission-critical remote switching applications. Solid-state non-latching relays are utilized for the highest level of long-term system reliability and trouble-free operation; electromechanical relay switching is not employed. The relay contacts automatically default to a normally-open state in the event of a loss of prime operating power or a loss of the received optical signal. These receiver modules incorporate status indicating LEDs for rapidly providing a local indication of each contact closure channel, optical link continuity, and operating power. Packaged in the exclusive ComNet ComFit housing, these units may be either shelf or rack-mounted, or may be DIN-rail mounted by the addition of ComNet model DINBKT1 Adaptor Plate Kit. Industrially hardened and rated for operation from -40 to +75 degrees C, the FDC8NLR may be deployed in virtually any unconditioned out-of-plant or trackside/ roadside environment, and voltage transient protection is provided across the operating voltage input and relay contact output rails. Plug-and-play design ensures ease of installation and operation, and no optical or electrical adjustments are ever required.
