Woodward 5437-672 Dual-Channel Bidirectional Actuator Drive Module

Product Description

Woodward 5437-672 is a dual-channel bi-polar actuator driver module for MicroNet and MicroNet TMR control systems. It is designed for turbine and compressor control systems. The outputs can be software-configured as proportional or integrating signals to drive electro-hydraulic actuators and fuel control valves. This module supports rack hot-swap, compatible with Woodward TMR triple modular redundant architecture. It is equipped with built-in fault diagnosis and channel detection, with high anti-interference performance. It is a dedicated I/O module for turbine speed regulation and valve position controlWoodward.
