Woodward 5437-672 NetCon Field Terminal Module

Description

Key Technical Specifications

Woodward’s own 5009FT documentation lists 5437-672 as the FTM associated with the 5501-432 Actuator Controller Module and 5417-041 cable. The 37-pin screw-clamp configuration is documented by secondary equipment records.

Product Introduction

The Woodward 5437-672 is a NetCon Field Terminal Module used as the field-side termination interface for Woodward actuator-controller hardware. In the 5009FT MicroNet+ TMR configuration, Woodward pairs this FTM with the 5501-432 two-channel actuator controller through the 5417-041 interconnection cable.

This is not a standalone CPU, governor, or actuator driver. It is an interface/termination component within the turbine control architecture. Replacement should therefore be based on the complete installed-system configuration, connector arrangement, associated controller, and hardware revision rather than the part number alone.

Installation & Configuration Guide

Stage 1: Pre-Installation Preparation — 5–10 Minutes

⚠️ Safety First: The 5437-672 is used in turbine control equipment. Place the turbine and associated actuator system in the site’s approved safe state before disconnecting control wiring. Follow the plant’s lockout/tagout and turbine-control maintenance procedures.

Tools Required:

• ESD wrist strap
• Appropriate screwdriver
• Digital multimeter
• Wire labels
• Smartphone or camera
• Current Woodward system drawings

Data Backup:

1. Record the complete 5437-672 nameplate information.
2. Photograph the terminal wiring before disconnecting anything.
3. Record the associated actuator-controller module number.
4. Verify whether the installed controller is 5501-432.
5. Record the interconnection cable identification.
6. Photograph terminal positions, wire numbers, jumpers, and shield connections.

⚠️ Do not rely on wire color or memory. Actuator-control wiring should be copied from the existing installation drawings and terminal photographs.

Stage 2: Removing the Old Module — 5 Minutes

1. Confirm the turbine control system is in the approved maintenance state.
2. Isolate power according to the Woodward system maintenance procedure.
3. Label each field wire before removing it.
4. Photograph both sides of the terminal wiring.
5. Disconnect the field wiring without pulling on individual conductors.
6. Disconnect the associated interconnection cable.
7. Release the module from its mounting arrangement.
8. Inspect terminals, connectors, cable ends, and cabinet wiring for corrosion or mechanical damage.

⚠️ Keep the removed 5437-672 available until commissioning is complete. It provides a direct physical reference if a terminal position or wiring detail is questioned.

Stage 3: Installing the New Module — 5–10 Minutes

1. Verify the complete part number: 5437-672.
2. Compare the replacement module’s connector and terminal arrangement with the removed unit.
3. Inspect terminals for bent contacts, damaged screw clamps, or contamination.
4. Install the FTM in its original mounting position.
5. Reconnect the associated interconnection cable.
6. Reconnect field wiring according to the original drawings and photographs.
7. Verify every conductor against the terminal schedule.
8. Check shield and grounding connections carefully.

Woodward’s documentation identifies the 5437-672 as the FTM associated with the 5501-432 two-channel actuator controller, so the controller/cable combination should be verified before commissioning.

Self-Checklist:

• 5437-672 part number verified
• Hardware/revision markings recorded
• 37-pin interface inspected
• Terminal wiring matches drawings
• 5501-432 compatibility verified where applicable
• 5417-041 cable verified where applicable
• Shield/ground connections checked
• All terminals mechanically secure

Stage 4: Power-On & Testing — 10–20 Minutes

1. Perform a final wiring inspection before energizing the control system.
2. Check for unintended shorts between relevant control and field circuits.
3. Restore power according to the approved Woodward commissioning procedure.
4. Check the associated actuator-controller status.
5. Verify that the controller recognizes its connected field interface.
6. Check actuator feedback and command signals using the approved commissioning procedure.
7. Perform controlled actuator testing where permitted.
8. Confirm normal turbine-control diagnostics.
9. Compare actual signal behavior against the expected engineering values.
10. Record the replacement and test results in the maintenance record.

⚠️ Do not use the FTM as evidence that the complete actuator loop is healthy. A successful physical replacement does not prove that the actuator, controller, cable, field wiring, feedback device, and control logic are all operating correctly.

Frequently Asked Questions (FAQ)

What is the Woodward 5437-672?

The 5437-672 is a Woodward NetCon Field Terminal Module (FTM) used for actuator-controller field termination. It is associated with Woodward turbine-control hardware rather than functioning as an independent CPU or governor.

Which controller is associated with the 5437-672?

Woodward’s 5009FT MicroNet+ TMR documentation pairs the 5437-672 FTM with the 5501-432 two-channel Actuator Controller Module and 5417-041 cable.

Is the 5437-672 the actuator driver itself?

No. The distinction matters during replacement. Woodward identifies the 5501-432 as the two-channel actuator controller, while 5437-672 is the associated field termination module.

Is the Woodward 5437-672 obsolete?

Available equipment records identify the 5437-672 as discontinued, so procurement should be handled as a legacy-part requirement. Current Woodward documentation remains the appropriate reference for system compatibility.

Can I substitute another Woodward FTM with a similar appearance?

Do not assume interchangeability. The FTM is part of a defined actuator-control architecture. Verify the exact part number, terminal arrangement, associated actuator controller, cable, and system revision before approving a substitute.

Does replacing the 5437-672 require software configuration?

The 5437-672 itself is a field termination/interface component, not the primary programmable controller. However, replacing it can affect the actuator signal path. The associated controller and turbine-control application should therefore be checked during commissioning.

What should I verify before purchasing a 5437-672?

At minimum, verify:

• Exact part number: 5437-672
• Installed-system family
• Associated actuator controller
• Connector and terminal arrangement
• Hardware/revision markings
• Physical condition
• New Original / New Surplus / Refurbished status
• Test documentation
• Warranty and return terms

For a legacy turbine-control part, matching the complete installed configuration is more important than simply finding a part number that looks similar. Woodward’s published system documentation provides the strongest compatibility reference.
