⚙️ NetCon Field Termination Function
The 5437-672 serves as an interface between field wiring and the associated control system.
Field terminal modules are useful because they move the field wiring connection point away from the main processor or control hardware. This can make cabinet wiring more organized and allows technicians to disconnect or replace system components with less disturbance to field wiring.
Typical connected equipment can include:
🔹 Sensors
🔹 Actuators
🔹 External status contacts
🔹 Control signals
🔹 Industrial field devices
🔹 System interconnections
The exact signals handled by the module depend on the installed Woodward control-system configuration. For this reason, the module should not be described as a standalone PLC CPU or a general-purpose I/O processor.
🔌 37-Pin Connector Interface
One important identification feature of the 5437-672 is its 37-pin interface.
This connection arrangement links the field terminal module with the corresponding Woodward control hardware or system cable assembly. The module also provides screw-clamp terminals for field-side wiring connections.
Before replacing the module, technicians should verify:
🔹 Connector type
🔹 Pin arrangement
🔹 Cable orientation
🔹 Terminal numbering
🔹 Field wiring identification
🔹 Hardware revision
A connector that appears physically similar should not automatically be considered electrically compatible.
🏭 Typical Applications
The Woodward 5437-672 can be encountered in industrial control installations where NetCon field termination hardware is used.
Typical applications include:
🔹 Turbine control systems
🔹 Industrial engine control
🔹 Prime mover automation
🔹 Distributed control cabinets
🔹 Field sensor connections
🔹 Actuator wiring interfaces
🔹 Legacy Woodward automation systems
🔹 Control-system maintenance projects
🔹 Industrial spare-parts inventory
🔹 Long-term support of installed control systems
Woodward documentation places the 5437-672 within the NetCon field-terminal hardware environment associated with Woodward control systems.
🛠 Installation and Replacement Guide
1. Confirm the complete part number
Verify that the existing module is marked:
5437-672
Also compare the revision marking. For this unit, the identified revision is:
REV G
A different revision should be checked for hardware and system compatibility before replacement.
2. Record the original wiring
Before removing the module, document:
🔹 Terminal connections
🔹 Wire numbers
🔹 Connector position
🔹 Cable orientation
🔹 Module location
🔹 Revision marking
Photographing the installation before removal can reduce the risk of wiring errors.
3. Isolate the control system
Follow the approved lockout and electrical isolation procedure for the host equipment.
4. Inspect the replacement module
Check:
🔹 DB-style connector condition
🔹 Screw terminals
🔹 Terminal markings
🔹 PCB or internal electronics
🔹 Mounting points
🔹 Signs of corrosion
🔹 Mechanical damage
🔹 Loose components
5. Reconnect the field wiring
Reconnect each conductor according to the original terminal documentation.
Do not transfer wiring based only on connector position or cable color.
6. Perform system testing
After installation, verify:
🔹 Control-system diagnostics
🔹 Field-device signals
🔹 Associated actuator or sensor circuits
🔹 Alarm conditions
🔹 Communication status
🔹 Overall system response
🔄 Compatibility Notes
The 5437-672 is a specific Woodward NetCon Field Terminal Module.
Other Woodward terminal modules may look similar but can have different functions, channel counts, connector arrangements, and system assignments.
Before replacement, compare:
🔹 Complete part number
🔹 Hardware revision
🔹 DB37 connector arrangement
🔹 Terminal configuration
🔹 Installed control platform
🔹 Field wiring assignment
🔹 Associated controller hardware
🔹 Original system documentation
The part number should be treated as the primary replacement reference. Similar NetCon hardware is not automatically interchangeable.
