Woodward 5501-1432 Dual Channel Actuator Control Module

Product Description

The Woodward 5501-1432 is a dual-channel actuator drive module for Woodward MicroNet TMR turbine control platform. It provides high-precision proportional drive signals for hydraulic or electro-hydraulic actuators, receives setpoint commands from the main controller, and feeds back actuator position signals for closed-loop regulation. It is widely used in steam turbine, gas turbine and compressor control cabinets for power plants and petrochemical facilities.

Features

• Two independent actuator drive channels, each channel supports position feedback closed-loop control
• Max output load current 200mA, fast response time ≤ 1ms for high dynamic valve regulation
• Supports RS485 communication interface to interact with MicroNet main control board
• On-board channel diagnostics, short-circuit, open-loop and actuator fault detection
• Rack-mounted slot installation, powered by system backplane, hot-swap capable
• Status LED indicators for power, communication, channel active and fault alarm
• Industrial wide temperature and anti-vibration design, suitable for turbine room harsh EMC environment
• Matched with proportional hydraulic actuators for steam/gas turbine governing valves

Application Scenarios

• Woodward MicroNet TMR 5009FT fault-tolerant steam turbine control system
• Gas turbine, compressor and generator set governing valve control
• Power plant, chemical plant and refinery critical turbine control cabinets
• Hydraulic actuator closed-loop drive and position monitoring
• TMR control rack maintenance, spare parts replacement and system retrofit
