Comnet FDC80NLRS1 8-Channel Supervised Contact Closure Receiver

8 Channel Contact Closure Receiver, Non-Latching, sm, 1 fiber.

The ComNet FDC80 Series transmitter and receiver units provide of up to eight independent supervised or unsupervised dry switch relay closures over a optical fiber. Microprocessor-based logic transmits the information in packets that are ordered encoded, ensuring extremely robust reliable transmission. garbled, out sequence with bit errors will not cause random changes state FDC80R unit relays. System faults displayed via LED status indicators, user-programmable summary fault alarm contacts triggered unit. External shunt resistors included for each input channels, supervision.
