Description

Product Overview

The Woodward 5466-1050 is a MicroNet Simplex 48/24 High-Density Discrete I/O Smart-Plus module for Woodward MicroNet control systems. Woodward identifies it as a simplex digital I/O module providing 48 discrete inputs and 24 discrete outputs. It is intended for turbine and other critical rotating-equipment control applications where a high concentration of discrete signals must be interfaced with the controller. The module is designed for installation in either full-size or narrow MicroNet chassis and uses compatible field termination modules. Woodward documentation also identifies software compatibility requirements for different coder revisions, so the installed application version should be checked during replacement planning.

Technical Specifications — 5466-1050

Woodward 5466-1050

Woodward lists 5466-1050 as the MicroNet Simplex 48/24 HDDIO Smart-Plus module. Available technical references also identify it as a no-calibration module with either full-size or narrow chassis compatibility.

Key Features and Benefits — 5466-1050

• 48 discrete inputs and 24 discrete outputs in one high-density module.
• Simplex architecture for compatible MicroNet control systems.
• Smart-Plus design intended for higher-density discrete signal handling.
• Compatible with established MicroNet field termination arrangements.
• No potentiometer adjustment or routine field calibration is required.
• Suitable for turbine, compressor, and generator-control applications.
• Supports lifecycle replacement where legacy MicroNet hardware remains in operation.
• Woodward documentation identifies software/coder compatibility requirements, so system version should be verified before installation.

For spare-parts control, I would keep the module together with its applicable FTM and configuration records. The hardware is only one part of a successful I/O replacement.

Installation and Maintenance — 5466-1050

Before replacement, isolate the relevant MicroNet power supplies and follow Woodward’s approved maintenance procedure. Record the chassis slot, FTM connections, software/coder revision, and I/O configuration before removing the existing card.

Inspect the card-edge connector, field termination cables, chassis guides, and module indicators for contamination or physical damage. After installation, verify representative input and output channels individually before returning the turbine-control system to normal operation. Personally, I would confirm the coder/software compatibility first; Woodward specifically documents software-version restrictions for this module family.

Product Warranty — 5466-1050

Warranty coverage depends on supplier, condition, testing status, and purchase agreement. For used or refurbished inventory, request functional-test documentation covering representative digital input and output channels and confirm the hardware revision. The Woodward 5466-1050 should be matched to the MicroNet chassis, field termination arrangement, application software, and turbine-control configuration before commissioning.
