Comnet FDC80TS1 8-Channel Supervised Contact Closure Transmitter

8 Channel Contact Closure Transmitter, sm, 1 fiber.

The ComNet FDC80TS1 transmitter and receiver units provide of up to eight independent supervised or unsupervised dry switch relay closures over a optical fiber, 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. 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. is offered both latching non-latching configurations. External series shunt resistors included each input channels, supervision.
