Industrial Current Sensing Solution – WOODWARD 5466-026 | NETCON Series
In power generation and turbine control environments, accurate real-time current measurement is not optional — it is the foundation of safe, stable operation. The WOODWARD 5466-026 NETCON Duplex Current Input module delivers dual-channel analog current acquisition engineered specifically for WOODWARD’s NETCON distributed control platform, trusted by plant engineers across gas turbines, steam turbines, and generator protection systems worldwide.
When a turbine control loop demands sub-millisecond signal fidelity and zero cross-channel interference, the 5466-026 is the module engineers specify by name.
Where This Product Is Used
The WOODWARD 5466-026 is deployed in mission-critical environments where duplex (redundant) current signal acquisition is mandatory:
- Gas Turbine Control Systems — Fuel flow metering, compressor inlet current monitoring, and load-sharing feedback loops in GE, Siemens, and Solar Turbines installations running WOODWARD NETCON controllers.
- Steam Turbine Governor Systems — Speed and load current feedback for steam admission valve control in combined-cycle power plants (CCPP).
- Generator Protection Panels — Differential current sensing for generator stator protection, integrated with NETCON-based excitation control.
- Compressor Control Cabinets — Anti-surge and performance control loops in centrifugal and axial compressors at LNG terminals and petrochemical plants.
- Marine Propulsion Control — Dual-redundant current input for diesel-electric propulsion management systems on offshore vessels and naval platforms.
- Hydro Turbine Governors — Gate position current feedback in hydroelectric generating units with WOODWARD NETCON architecture.
If your facility runs WOODWARD NETCON and requires certified duplex analog input capability, the 5466-026 is the OEM-specified solution.

Application-Specific FAQ
Q: Can the 5466-026 replace a single-channel current input module in my NETCON rack?
A: The 5466-026 is a duplex (dual-channel) module. It occupies a single rack slot but provides two independent input channels. Verify your rack slot assignment and NETCON configuration file before substituting for a single-channel variant.
Q: Is the 5466-026 compatible with WOODWARD NETCON II and NETCON III platforms?
A: Compatibility depends on the specific NETCON generation and backplane revision. Konmask recommends providing your full NETCON system part number and software version for confirmation before ordering.
Q: Can this module accept 0–20 mA or 0–10 V signals?
A: The 5466-026 is designed for 4–20 mA current loop inputs. For voltage input or alternative current ranges, consult WOODWARD’s NETCON analog input module catalog for the appropriate variant.
Q: What happens if one channel fails in duplex mode?
A: In a properly configured NETCON duplex loop, the controller detects the channel fault via diagnostics and continues operating on the healthy channel. Alarm annunciation and failover behavior depend on your NETCON application software configuration.
Q: Do you provide a test report with the module?
A: Yes. All surplus and refurbished units shipped by Konmask include a functional test report. OEM new units include WOODWARD factory documentation where available.
Q: Can Konmask supply the complete NETCON rack assembly?
A: Yes. Konmask specializes in complete WOODWARD NETCON system sourcing including racks, CPU modules, I/O modules, and power supplies. Contact us with your full BOM for a consolidated quotation.
