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.
Key Features
- Indicating LEDs for monitoring power, contact closure status, and summary fault
- Automatic resettable solid-state current limiters
- Microprocessor-based logic and latching relays in the receiver unit
