ComNet FDC80T485 Transmitter - Contact closure extender - transmitter - serial RS-485 - up to 1500 ft - 1U
- Microprocessor-based logic and latching relays in receiver unit eliminate random contact closure status in the event of loss of link or loss of prime operating power
- Designed to meet full compliance with the environmental requirements
- ComFit standard form factor is interchangeable between stand-alone or rack mount use
- Standard ComFit models are hot-swappable
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. 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.
