• Regenerates weak optical signals to extend remote I/O and inter‑area links.

• LED status lights enable fast on‑site troubleshooting.

• Rugged construction for 24/7 continuous operation in power, water treatment, and petrochemical plants.

Applications

• Extend fiber links between main control rooms and remote I/O stations.

• Long‑distance DCS signal relay in large power plants.

• Noise isolation for DCS networks in petrochemical and water treatment facilities.

• Direct replacement for legacy Westinghouse WDPF fiber repeaters.

Installation & Operation

1. Mount on DIN rail or control panel.

2. Connect 115 VAC power; confirm power LED is on.

3. Insert multi‑mode fiber into TX/RX ports; verify link LED.

4. Check data transmission status via TX/RX LEDs.

Troubleshooting

• No power: Check 115 VAC wiring and power circuit.

• Link down: Inspect fiber connections, cable breaks, or port damage.

• Poor signal: Avoid tight fiber bends; re‑route cables away from interference sources.
