System compatibility

5432-157 belongs to Woodward MicroNet turbine control system family,matched with MicroNet rack CPU and I/O modules.Widely used in gas turbine,steam turbine and generator control cabinets.This is a discontinued legacy redundant power supply module for power unit maintenance spare replacement.

Function

5432-157 serves as Woodward plug-in redundant power supply module.It provides regulated 24V DC power for all boards inside MicroNet control rack,adopts dual power current sharing design.When one power circuit fails,the other circuit automatically takes over to maintain continuous power shturl.cc integrates multiple protection functions including overvoltage,overcurrent and short-circuit protection,and uploads power status and fault information to main controller through backplane bus.It is the core power supply unit of Woodward MicroNet turbine control rack.

Installation

Insert 5432-157 into control rack slot,lock the handle.Complete input power wiring according to wiring drawing.Check input voltage and rack grounding before power-on.

Interface

‑Rack backplane bus connector

‑DC input terminal block

‑Power status LED indicator

‑Fault alarm signal terminal

Circuit feature

Dual redundant current sharing circuit,built-in surge and ESD protection design.Stable power output,strong anti-interference performance for power plant cabinet environment.

Feature

5432-157 is obsolete Woodward series spare part.Typical failures include no output,output voltage drift,overcurrent shutdown,fault indicator alarm.Check power circuit and backplane connector pins before replacement.This module must match corresponding MicroNet rack system,direct substitution without inspection is not recommended.

Diagnostic

When power loss,output abnormal or internal fault occurs,the module will trigger system power fault alarm and report fault code to main controller.

Built‑in function

Rack internal board power supply,redundant current sharing,overload and short-circuit protection,power status monitoring,used as Woodward MicroNet series rack power supply module spare replacement.

Product Brief

5432-157 is Woodward old turbine series redundant rack power supply module for gas/steam turbine generator sets and power automation equipment.Confirm MicroNet rack model matching before ordering.ESD protection required during handling and installation.
