5437-523C | Woodward MicroNet Series | Analog Field Terminal Module

Product Overview

The Woodward 5437-523C Field Terminal Module is an analog termination interface engineered for MicroNet and MicroNet Plus control platforms. It acts as the physical and electrical boundary between field-level devices and the controller’s I/O electronics, delivering stable signal transfer, electrical isolation, and reliable long-term operation in mission-critical control systems.

Designed for turbine, engine, and generator control applications, this module ensures clean analog signal routing while protecting sensitive controller hardware from noise, grounding issues, and transient disturbances commonly found in industrial environments.

​Functional Description

The 5437-523C is a standard analog FTM equipped with screw-clamp terminals and a 37-pin system connector. It supports accurate and low-noise transmission of analog output signals when paired with compatible MicroNet I/O modules. The design emphasizes electrical integrity, ease of wiring, and maintainability within control cabinets.

This module is typically installed adjacent to MicroNet I/O racks and serves as the primary termination point for actuators, valves, and other analog-driven field devices.
