System Architecture & Signal Flow
The 8200-188 integrates into a standard closed-loop governor or fuel control architecture as follows:
- Speed/Load Sensor → transmits process variable to the WOODWARD controller (e.g., 505, 2301, MicroNet).
- Controller Output → generates 4–20 mA demand signal to the 8200-188 actuator.
- Actuator → converts electrical demand to precise rotary shaft displacement, driving the fuel valve or rack.
- Position Feedback → internal LVDT or potentiometer returns actual position to the controller for closed-loop correction.
- Fuel Valve / Rack → modulates fuel flow in direct proportion to actuator shaft angle.
This architecture supports both isochronous (constant speed) and droop (load-proportional) control modes depending on controller configuration.

Technical FAQ
Q: Is the 8200-188 compatible with WOODWARD 2301A and 505 controllers?
A: Yes. The 8200-188 is designed to interface with standard WOODWARD governor controllers using 4–20 mA actuator output channels. Verify wiring polarity and current range against your specific controller manual.
Q: What is the difference between the 8200-188 and other 8200-series variants?
A: The 8200 series covers a range of torque ratings and shaft configurations. The -188 suffix designates a specific torque/stroke combination. Contact Konmask for cross-reference assistance if you are evaluating alternative variants.
Q: Can this actuator be used in ATEX/hazardous area zones?
A: The standard 8200-188 is not ATEX-certified. For hazardous area applications, consult WOODWARD’s EX-rated actuator product line or contact Konmask for guidance.
Q: What is the typical lead time?
A: In-stock units ship within 1–3 business days. Ex-stock or sourced units typically require 5–15 business days. Contact us for real-time availability.
Q: Do you provide installation support?
A: Yes. Konmask technical support can provide wiring diagrams, commissioning checklists, and remote guidance for qualified engineers. Contact [email protected].
