Woodward 8402-319 / 8402-119 Termination Assembly Set – Clean, reliable field wiring interface for MicroNet-based controls
The Woodward 8402-319 and 8402-119 are commonly paired as a termination assembly set that routes field signals to the matching rack module via a dedicated interface cable. From my experience, this kind of TA set is the unsung hero in turbine and compressor cabinets—clear labeling, robust terminals, and a direct, error‑resistant path from plant devices to the controller. You might notice project BOMs list both numbers together; it typically means you’re getting the board plus the correct cable or mating hardware, which saves time during panel build and FAT.

Application Fields
This set is typically used wherever Woodward turbomachinery controls interface to hardwired plant signals. Practical use cases:
- Gas & steam turbine cabinets – landing limit switches, permissives, trips, and actuator feedback.
- Compressor anti‑surge and protection – organizing I/O for transmitters, valves, and shutdown paths.
- Generator sets – breaker status/control, sync permissives, and balance‑of‑plant signals.
- Refining / petrochemical / LNG – high channel‑count terminations in SIL‑applied architectures.
- Power & utilities – clean hand‑off to DCS/SIS via hardwired interfaces.
Advantages & Value
- Faster panel build – Predefined pinouts and labeled terminals typically cut wiring time and rework.
- Lower integration risk – Native fit to the matching Woodward I/O reduces cross‑termination errors.
- Maintainable layout – Clear channel numbering speeds loop checks, SAT, and proof testing.
- Noise‑aware design – Proper shield/earth provisions help keep low‑level signals clean.
- Spares strategy – Keeping like‑for‑like TA and cable sets on the shelf minimizes outage delays.
Installation & Maintenance
- Cabinet & routing – Mount on a flat, ventilated panel; allow bend radius for the interface cable and room for ferrules/markers.
- Wiring practices – Use ferruled conductors; separate low‑level I/O from power/VFD runs; bond shields per site grounding policy.
- Safety – Apply LOTO on field circuits; if the associated I/O is trip‑critical, follow site bypass rules before any work.
- Torque & inspection – Re‑torque terminals after initial heat cycles; check for insulation nicks and label legibility.
- Documentation – Keep the pinout/map with the cabinet file; it appears that this prevents mis‑patching during fast turnarounds.
Quality & Certifications
- Compliance – Typically used within CE‑compliant cabinet assemblies; RoHS‑conformant components are common.
- Use in SIL projects – Applied as part of Woodward architectures that support IEC 61508 SIL levels when engineered per the safety manual.
- Warranty – 365 days from delivery.
A commissioning engineer told me after a turbine outage, “Having the correct TA and cable pair meant every loop landed first‑time—no chasing cross‑wires.” That’s the everyday benefit these 8402‑319 / 8402‑119 sets tend to deliver.
