Comnet FDC80NLR485 8 Channel Contact Closure Receiver (RS485), Non-Latching

The FDC80NLR485 from Comnet is a 8 Channel Contact Closure Receiver (RS485), Non-Latching. The ComNet™ FDC80 Series transmitter and units provide transmission of up to eight independent supervised or unsupervised dry switch relay closures over single optical fiber, any two-wire RS-485 copper circuit. Microprocessor-based logic transmits 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. supervising function FDC80T allows for detection short open circuit conditions, normally closed inputs supported. System faults displayed via LED status indicators, user-programmable summary fault alarm contacts triggered unit. offered both latching non-latching configurations. External shunt resistors included each input channels, supervision.
