Key Features

• Fully compliant with native Ovation and WDPF communication protocols, plug-and-play without additional configuration.

• Fiber optic transmission provides complete galvanic isolation, which effectively mitigates EMI and RFI interference in harsh industrial environments.

• Optimized transceiver unit delivers more stable signal performance and longer service life.

• Restores weakened optical signals to realize long-distance communication between control rooms and remote I/O cabinets.

• Clear LED indicators enable rapid status inspection and on-site fault diagnosis.

• Rugged industrial design supports 24-hour non-stop operation.

• Directly interchangeable with 3D04106G01, 3D04106G02 and 3D04106G04 for easy on-site replacement.

Applications

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

• Serve as signal relay for long-distance DCS network in large power plants.

• Provide anti-interference and isolation solutions for DCS networks in petrochemical and water treatment facilities.

• Replace aging fiber repeaters for routine maintenance of legacy Ovation and WDPF systems.

Installation and Operation

1. Install the module onto a standard DIN rail or control panel.

2. Connect the 115 VAC power cable and confirm the power LED lights up.

3. Connect multi-mode optical fibers to the corresponding transmit and receive ports.

4. Check link status via LED indicators and confirm normal data transmission.

Troubleshooting

• No power: Check AC power wiring and power supply circuit.

• Link failure: Inspect fiber connections, cable damage and port conditions.

• Unstable signal: Prevent sharp bends of optical fibers and keep cables away from strong interference sources.
