Description
Product Overview
The Woodward 5441-694 is a discrete I/O field termination module used to interface field wiring with compatible control-system hardware. Its documented 24-input/12-output configuration makes it relevant to applications that collect discrete status signals and provide relay-driver output connections. The module is a termination/interface component; it should not automatically be treated as a standalone programmable controller or as a direct substitute for the controller’s I/O processing module.
In an industrial installation, discrete inputs may represent equipment status, switch states, permissive conditions, or alarm contacts. Output circuits may serve control or relay-interface functions, depending on the system design. The actual field signal types, voltage levels, output ratings, and isolation arrangements must be checked against the applicable wiring diagram. The 24-input/12-output designation alone does not establish that every channel can accept the same signal type or switch every load.
Procurement requires particular attention to the complete interface assembly. Woodward documentation associates the 5441-694 with high-density discrete I/O termination and cable arrangements, while the catalog also lists a related 5441-693 module with a different output description. Do not interchange these modules simply because the part numbers are adjacent. Verify the controller generation, I/O module, mating cable, terminal arrangement, and revision before approving a replacement.
Product Introduction
The Woodward 5441-694 provides a field termination interface for compatible discrete control signals. It is relevant to industrial automation and engine or turbine-control installations where dependable wiring between field devices and the control system is essential.
Before installation, compare the existing module’s label and revision with the replacement. Confirm the terminal assignments, wiring harness, input characteristics, and relay-driver requirements using the equipment documentation. For shutdown or other safety-related circuits, follow the approved engineering and commissioning procedures rather than relying on a visual match alone.

Frequently Asked Questions
Q1: What is the Woodward 5441-694 used for?
It is a high-density discrete I/O field termination module with a relay-driver interface, documented for 24 inputs and 12 outputs.
Q2: Is the 5441-694 a complete PLC or controller?
No. It is an I/O termination/interface component used within a compatible control-system arrangement. Confirm which controller and I/O hardware it must connect to.
Q3: Can it replace a Woodward 5441-693?
Do not assume direct interchangeability. Although the two models have related descriptions, their interface and wiring requirements must be compared against the system documentation.
Q4: What input voltage does the 5441-694 support?
The exact input voltage range was not independently verified. Check the applicable wiring diagram and technical manual before connecting field signals.
Q5: What should be verified before ordering?
Confirm the part number, revision, controller platform, mating cable, connector configuration, and required input/output electrical characteristics. Ask the supplier for photographs of the actual module.
Q6: Can the module be hot-swapped?
Hot-swap support for this exact module and installed configuration has not been verified. Follow the manufacturer’s instructions for isolation and replacement; do not remove or insert the module under power unless the documented procedure explicitly permits it.
Q7: What testing should be requested for a used module?
Request a visual inspection report, connector and terminal checks, and a functional test report showing the input and output tests performed. If the module is part of a critical control or protection system, confirm the acceptance procedure with the responsible controls engineer before returning the equipment to service.
