Product Description

The 5466-257 is a high-precision analog I/O expansion module engineered by Woodward for use in MicroNet control platforms, including TMR and Simplex architectures. This module is designed for high-speed deterministic control of large prime movers such as steam and gas turbines.

The module provides a centralized interface for multiple analog process signals, converting field sensor data into digital control information with minimal latency. It is optimized for turbine control loops where precise fuel, actuator, and process regulation is required.

The 5466-257 is built for high-density control cabinets and supports multiple control loops from a single chassis slot. Integrated onboard diagnostics continuously monitor A/D and D/A conversion integrity as well as output driver health, helping prevent control drift that could lead to combustion inefficiency or mechanical stress in rotating machinery systems.

Technical Specifications

Item Specification

Application Scenarios

The 5466-257 is widely deployed in:

  • Gas turbine fuel valve control systems

  • Servo actuator positioning loops

  • Lube oil pressure monitoring

  • Cooling water and auxiliary process control

Its rugged design allows installation in turbine control cabinets, offshore platform engine rooms, and other harsh industrial environments where vibration and thermal cycling are common.

Technical FAQ

Can the 5466-257 be used in TMR configurations?
Yes. The module is fully compatible with MicroNet TMR architectures, where three redundant control channels operate using voting logic to prevent single-point failures from causing turbine shutdowns.

Does this module support HART communication?
No. The 5466-257 is designed for high-speed analog signaling only. Applications requiring HART over 4–20 mA communication should use a dedicated HART-capable I/O module from the MicroNet ecosystem.
