- Industrial control network for steam turbine, generator control panels
- Oil & gas compressor control systems
- Legacy power system retrofit and spare replacement
Installation & Maintenance Notes
- Mount on DIN rail inside EMC shielded control cabinet, keep away from high voltage cables.
- Use shielded CAT5e industrial Ethernet cable for all field connections.
- Connect both redundant 24VDC power supplies for maximum reliability.
- Verify cable termination and ground bonding before power-up.
- Periodically inspect for dust buildup, loose RJ45 connections and power terminal corrosion.
- This is legacy turbine networking hardware; confirm firmware and network topology compatibility before replacement.
