Transmit 4 Digital Inputs Bi-Directionally Over Fiber​

The system provides transmission of four (4) independent input signals on each end over fiber optic cable in both directions. Applications include alarm event triggering, building automation, environmental control systems, fire & alarm systems, gate control, traffic signal control equipment, and more. A complete system requires two (2) units, a 24-48VDC power source on each end, and two (2) matching SFP Transceivers.

Each unit features four (4) input terminals, four (4) output relays, a NC/NO alarm contact for system monitoring, and convenient LED indicators to view system status.
