Comnet FDC80R485 8-Channel Supervised Contact Closure Receiver

8 Channel Contact Closure Receiver (RS485).

The ComNet FDC80 Series transmitter and units providetransmission of up to eight independent supervised or unsupervised dry switch relay closures over any two-wire RS-485 copper circuit. 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. is offered both latching non-latching configurations. External shunt resistors included for each input channels, supervision.
