Description
Woodward 5441‑413 Relay Interface Module
Product Overview
5441‑413 is a legacy multi‑channel relay interface module manufactured by Woodward, designed for MicroNet / NetCon turbine control systems. It provides galvanic isolation between turbine controller logic circuits and field‑side discrete devices, converting controller logic signals into relay contact outputs for trip circuits, solenoid valves, alarm annunciators and auxiliary equipment. This is original US‑sourced hardware; OEM production has been discontinued, and it is mainly used as spare‑parts for existing gas‑turbine and steam‑turbine control retrofits and maintenance.
Typical Applications
- Gas & steam turbine control system: Field signal isolation and relay output for Woodward MicroNet and NetCon control platforms
- Power‑generation units: Turbine trip logic, emergency shutdown loops, alarm signal output for power plant turbo‑generator sets
- Oil & gas industry: Turbo‑machinery safety interlock control for compressor drives
- Marine power equipment: Auxiliary engine and turbine control cabinet signal conditioning
- Brown‑field maintenance: Spare‑part replacement for existing installed Woodward turbine control cabinets; retrofitting of legacy turbine control systems

Key Features & Benefits
- High‑reliability galvanic isolation: Isolates controller logic from field‑side surge and noise, protects core turbine‑control electronics from field‑circuit interference.
- Multi‑channel relay output integration: Multiple SPDT relay contacts integrated on single module, reduces cabinet wiring and spare‑part varieties for turbine safety‑loop design.
- Proven turbine‑grade hardware: Designed for continuous 24‑hour operation in power‑plant and oil‑gas turbine‑control cabinets, validated for critical trip‑circuit applications.
- Direct compatibility with MicroNet / NetCon platform: Matches Woodward native turbine‑control backplane, no extra adapter required.
- Visual channel status indication: On‑board LED status indicators for each relay channel, simplifying on‑site fault diagnosis and commissioning work.
- Robust industrial mechanical design: Wide temperature tolerance, anti‑vibration construction for harsh power‑plant cabinet environments.
- Screw‑terminal field connection: Convenient field wiring, easy maintenance and replacement during equipment overhaul.
