Comnet FDC8ISOTM1 8-Channel Contact Closure Transmitter

8 Channel Contact Closure Transmitter, mm, 1 fiber, Isolated.

The ComNet FDC8ISOTM1 8-Channel Transmitter unit provides up to eight independent normally-open (NO) dry closures over one multimode or single-mode optical when used in conjunction with the companion model FDC8NLR Non-Latching Receiver FDC8R Latching units. Each of inputs are optically isolated at 1500V ground, for those applications where high stray transient voltages may exist. Microprocessor-based logic FDC8ISOT detects a customer-furnished switch closure, and encodes into robust data packets that mapped transmitted Receiver. received excessive bit errors will not result random changes relay resting actuated states, making this system ideal mission-critical remote switching applications. Plug-and-play design ensures ease installation operation, no electrical adjustments ever required.
