Product Core Background
Woodward 5441‑413 is a multi‑channel relay interface module belonging to the MicroNet Plus control system family, widely deployed within turbine and generator control cubicles. This interface hardware acts as the power‑buffered signal bridge between MicroNet main controller low‑level logic outputs and heavy‑load field equipment such as trip coils, alarm horns and auxiliary interlock circuits. It converts controller logic signals into reliable relay contact switching, delivering galvanic isolation between sensitive control electronics and high‑energy field wiring loops, and prevents back‑EMF and surge damage to main CPU boards.
As an end‑of‑life chassis‑mount spare part, it supports long‑term stable operation of existing power‑generation turbine control systems and avoids large‑scale control‑system hardware migration investment for plant assets.Woodward 5441‑413 is a chassis‑mount multi‑channel relay interface module for Woodward MicroNet Plus turbine‑generator control systems. It converts controller logic signals into isolated relay‑contact outputs for trip coils, alarm devices and safety‑interlock field loops, with built‑in status LEDs for channel‑level diagnostics.Providing galvanic isolation between sensitive controller electronics and heavy‑load field wiring, this legacy EOL spare is widely used for power‑plant gas/steam‑turbine control‑cabinet maintenance and component‑replacement projects.Verify full part‑number before ordering. Full‑channel functional test must be completed after installation.
- Chassis‑mount multi‑channel relay interface module, part number 5441‑413 for Woodward MicroNet Plus turbine‑generator control systems
- Transforms low‑level controller logic signals into isolated relay‑contact switching outputs for field‑side trip coils, alarm indicators and safety‑interlock loads
- Delivers galvanic isolation, protects main controller electronics from back‑EMF and surge transients generated by inductive field loads
- Front‑panel LED status indicators offer visual per‑channel diagnostic feedback for on‑site maintenance work
- Equipped with surge‑suppression hardware to mitigate contact‑switching interference within control cabinets
- Powered via MicroNet Plus rack backplane bus; designed for indoor cabinet‑mount operation, operating temperature ‑20 °C ~ +60 °C
- Mainly deployed for power‑plant gas‑turbine, steam‑turbine and captive‑power generator control‑cubicle signal‑distribution loops
- Critical legacy spare for existing MicroNet‑based control‑system maintenance, spare‑part replacement and control‑loop retrofit projects
- Full‑part‑number matching is mandatory; other 5441‑xx series relay modules cannot substitute due to different channel‑rating configuration
- Lockout‑tagout safety procedures required during replacement work
- Per‑channel trigger simulation and field‑load actuation validation test must be finished post‑installation
