Description

Product Overview

The Woodward 5466-348 is a Serial I/O (SIO) module used in Woodward NetCon 5000 control systems. Its primary role is to provide a communication interface between the control system and compatible digital actuator drivers, allowing actuator monitoring and control signals to be exchanged through RS-485 serial communication. Woodward documentation identifies this part as a NetCon 5000B SIO module, with three RS-485 ports intended for EM or GS/LQ digital actuator drivers. Each port can support one driver with a 5 ms update rate, making the module suitable for turbine and engine control applications where deterministic actuator communication matters.

For maintenance teams, this module is particularly relevant when replacing an installed legacy SIO card without redesigning the surrounding control architecture. Personally, I would verify the exact chassis, application configuration, driver type, and revision before installation, because Woodward has since introduced replacement SIO modules for newer MicroNet Plus systems.

Key Features and Benefits — 5466-348

• Three RS-485 communication ports for compatible digital actuator drivers.
• Supports fast cyclic communication suitable for turbine governor and actuator-control applications.
• Provides an interface between NetCon control hardware and field-level digital actuator equipment.
• Supports monitoring and control communication over the serial links.
• Fault-related communication functions can help identify an unavailable or malfunctioning driver.
• Suitable as a maintenance spare for existing NetCon 5000 installations.

The technical documentation also lists this part under the NetCon 5000B SIO architecture and associates it with the broader MicroNet/NetCon product family.

Related Models

5466-5007: Woodward MicroNet Plus SIO module with slide-lock connection. It is the newer replacement associated with the legacy 5466-348, but it is intended specifically for MicroNet Plus systems and Coder 4.06 or later.

5466-5006: MicroNet Plus SIO module using screw-post connections. It replaces another legacy SIO configuration and should not be treated as a universal substitute for every NetCon installation.

5501-471: Legacy Woodward SIO module with screw-post connections, listed alongside the 5466-348 in Woodward’s product-change documentation.

5466-409: NetCon/MicroNet CPU card used within the same general Woodward control-system ecosystem.

Installation and Maintenance — 5466-348

Before replacement, isolate the control system according to the plant’s approved maintenance procedure and record the existing module position, wiring, configuration, and revision information. Confirm that the replacement card matches the installed NetCon architecture.

Inspect the PCB, connectors, locking mechanism, and terminal interfaces for physical damage or contamination. After installation, verify RS-485 communication with each connected actuator driver and confirm that the control application recognizes the expected devices. Record communication status and fault indications during commissioning.

Because 5466-348 is a legacy component, compatibility should be checked against the actual system configuration rather than assumed from the part number alone. Woodward has formally identified newer SIO modules for migration in applicable MicroNet Plus systems.

Product Warranty — 5466-348

Warranty terms depend on the supplier, condition, and sales agreement. For critical turbine-control spares, confirm warranty coverage, serial-number traceability, test documentation, and return conditions before purchase. For obsolete or legacy hardware, request revision information and functional test records when available.

The Woodward 5466-348 remains a relevant identification for maintenance inventories supporting existing NetCon 5000B installations, particularly where an exact replacement is required to maintain the original control-system architecture.|
