Woodward 5466-409E / 5503-173A MicroNet CPU Control Module Assembly

Product Description

The 5466-409E is the main base unit, and 5503-173A is the matching sub-board component, forming a complete Woodward MicroNet Peak150 CPU control assembly. It is a simplex processor module for turbine and generator control systems, equipped with 233 MHz Pentium processor and 64 MB RAM. It executes governor logic, speed regulation, load control, signal acquisition and bus communication for gas turbines, steam turbines and generator sets. This model is obsolete, mainly supplied as spare parts for maintenance and retrofit of old MicroNet control cabinets.

Features

• 233 MHz processing core, 64MB RAM for control logic and data storage
• 24V DC power supply, working temperature range -40℃ ~ +70℃
• Supports MicroNet LinkNet / RTCNet bus communication with distributed I/O modules
• Integrated fault diagnosis, event logging and turbine protection logic operation
• 5503-173A sub-board is a mandatory matching component for 5466-409E to realize full function
• Designed for simplex control configuration, not for triple redundant TMR system by default
• Standard rack mounting for Woodward MicroNet chassis
• High anti-vibration and anti-interference performance for heavy-duty prime mover control

Application Scenarios

• Steam turbine and gas turbine governor control systems
• Generator set speed control and load sharing control cabinets
