ComNet FDC80 Series 8-Channel Supervised Contact Closure
The ComNet™ FDC80 Series contact closure transmitter and receiver units provide transmission of up to eight independent supervised or unsupervised dry switch or relay contact closures over a single optical fiber, or any two-wire RS-485 copper circuit. Microprocessor-based logic transmits the contact closure information in packets that are ordered and encoded, ensuring extremely robust and reliable transmission. Packets that are garbled, or packets out of sequence with transmission bit errors will not cause random changes of state in the FDC80R receiver unit relays. The supervising function in the FDC80T transmitter allows for the detection of short and open circuit conditions, and normally open or normally closed contact inputs are supported. System faults are displayed via LED status indicators, and user-programmable summary fault alarm contacts are triggered in the FDC80R receiver unit. The FDC80R receiver is offered in both latching and non-latching relay configurations. External series and shunt resistors are included for each of the 8 contact input channels, for contact supervision. Packaged in the exclusive ComNet ComFit housing, these units may be either wall or rack-mounted, or may be DIN-Rail mounted by the addition of model DINBKT1 adaptor plate. Fully compliant with the requirements of NEMA TS-1/TS-2, these industrially-hardened units are designed for use in virtually any out-of-plant environment.

ComNet 8-Channel Contact Closure Transmitter
The ComNet™ FDC8ISOT 8-Channel Contact Closure Transmitter 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 FDC8NLR Non-Latching Receiver or FDC8R Latching Receiver units. Each of the contact closure inputs are optically isolated at 1500V to ground, for those applications where high stray or transient voltages may exist. Microprocessor-based logic in the FDC8ISOT 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. These transmitter modules incorporate status indicating LEDs for rapidly providing a local indication of each contact closure channel 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 FDC8ISOT 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 rail. Plug-and-play design ensures ease of installation and operation, and no optical or electrical adjustments are ever required.
