WOODWARD Governor FT Series Technical Notes

Governor FT Full Catalog & Functionalities (SKU List)

The following SKUs represent verified components within the WOODWARD Governor FT and closely associated 5466/5501/5463 module families. Each entry reflects a distinct functional role within the control system architecture.

5466-256: Fault Tolerant Discrete I/O module; 24 VDC digital inputs and relay outputs for turbine sequencing logic.
5466-258: Discrete I/O expansion module; additional DI/DO channels for auxiliary equipment interfacing.
5466-270: Analog Input module; 4–20 mA process variable inputs for speed, pressure, and temperature signals.
5466-272: Analog Output module; 4–20 mA command outputs for valve positioner and actuator control.
5466-280: Speed/Frequency Input module; magnetic pickup and proximity probe inputs for turbine shaft speed sensing.
5466-290: Communication Adapter module; RS-422/RS-485 serial interface for MODBUS RTU host integration.
5466-300: Redundant Power Supply module; dual-input 24 VDC regulated backplane power with fault annunciation.
5466-310: CPU/Controller module; primary processing unit executing governor control algorithms and PID loops.
5466-320: Redundant CPU module; hot-standby processor for fault-tolerant bumpless transfer on controller failure.
5466-330: Backplane Bus Interface module; inter-module communication and I/O scan coordination.
5501-470: ProAct Digital Drive module; PWM actuator driver for WOODWARD ProAct series fuel control actuators.
5501-472: Actuator Output module; high-current driver for electro-hydraulic servo valves and linear actuators.
5463-100: Thermocouple Input module; Type J/K/T thermocouple signal conditioning for exhaust temperature monitoring.
5463-110: RTD Input module; 3-wire PT100 resistance temperature detector inputs for bearing and lube oil monitoring.
5463-120: Overspeed Detection module; hardware-independent trip relay for turbine overspeed protection per API 670.
5463-130: Load Sharing module; droop and isochronous load sharing interface for parallel generator applications.
5463-140: Valve Position Feedback module; LVDT signal conditioning for steam admission valve position verification.

Quality Control for the Governor FT Range

The Governor FT backplane architecture uses a proprietary parallel bus structure that requires module-level functional testing under simulated load conditions — bench continuity checks alone are insufficient to verify operational integrity. DriveKNMS applies the following verification protocol to all Governor FT modules:
