Why Choose the Original Model
- Factory-calibrated PID parameters optimized for WOODWARD actuator families
- Proven reliability in continuous-duty power generation environments
- Full OEM firmware and configuration software (WOODWARD Watch Window) support
- Traceable serial number and manufacturing date for warranty and compliance
- Reduced commissioning time vs. third-party alternatives
Typical Applications
- Gas turbine and steam turbine speed control
- Diesel and natural gas generator sets
- Compressor and pump drive regulation
- Marine propulsion governor systems
- Industrial co-generation plants
System Compatibility
- Actuators: WOODWARD TM series, EG series, and ProAct series electric actuators
- Speed Sensors: Magnetic pickup (MPU), 60-tooth gear standard
- HMI / SCADA: Modbus RTU via RS-232 adapter; compatible with most DCS front-ends
- Power Supply: 24 VDC nominal (18–40 VDC range)
- Panel Integration: DIN rail or panel-mount; standard 35 mm DIN rail bracket available
Selection Guide
Use the following criteria to confirm the 9907-164 is the correct model for your application:
- Actuator type: Confirm proportional electric actuator (not hydraulic) is in use
- Speed range: Verify MPU frequency falls within 100–25,000 Hz at rated speed
- Supply voltage: Confirm 18–40 VDC panel supply is available
- Communication need: RS-232 serial required; if CAN or Ethernet needed, consider 9907-838 or EasyGen series
- Environment: Standard -40°C to +70°C; for offshore/marine, request conformal-coated variant
- Redundancy: Single-channel unit; for dual-redundant systems, pair with WOODWARD 9907-165 in hot-standby configuration

Replacement & Compatibility FAQ
Q: Can the 9907-165 directly replace the 9907-164?
A: In most cases yes — the 9907-165 is pin-compatible and uses the same Watch Window software. Verify actuator output current rating before swapping.
Q: Is the 9907-164 compatible with hydraulic actuators?
A: No. This model drives proportional electric actuators only. For hydraulic systems, consider the WOODWARD 723 or 2301 series.
Q: Can I use a third-party equivalent without recalibration?
A: Third-party equivalents typically require PID re-tuning and actuator output mapping. Factory settings are not transferable.
Q: Do you supply refurbished units?
A: Yes. Refurbished units are available at reduced cost and carry a 6-month warranty. Please specify when requesting a quote.
Q: What documentation is included?
A: Standard shipment includes the unit, original datasheet, and test report. CE declaration and calibration certificate available on request.
