The ComNet 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. 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 high level of long-term system reliability and trouble-free operation. 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. Plug-and-play design ensures ease of installation and operation, and no optical or electrical adjustments are ever required.
