4. Product Introduction (Anti-Template)
The Woodward 8200-226 is a Servo Position Controller (SPC) designed to position a single-coil hydraulic or pneumatic actuator. It accepts a position demand via DeviceNet as the primary interface and supports a 4–20 mA analog demand as backup or alternative primary input.
The controller closes the position loop using feedback from single or dual transducers (typically LVDT/RVDT or DC devices). It drives the actuator coil with a configurable current output and includes automatic demand transfer between DeviceNet and analog signals. The unit is configured and monitored through a PC serial service interface using Woodward software. It replaces earlier models 8200-224 and 8200-225 and is used in turbine, engine, and industrial actuator control applications where precise closed-loop positioning is required. Exact revision, coating type, and configuration parameters must be verified when replacing an existing unit.

5. QC, Procurement & Logistics SOP
- Inbound Verification – Confirm full model number (8200-226), revision, coating type if specified, and connector condition. Photograph all labels.
- Functional Testing – Limited standalone testing is possible. Full validation requires connection to the actuator, feedback devices, and demand signals (DeviceNet and/or analog).
- QA & Packaging – Protect connectors and the electronics housing, clean according to electronics handling practices, and pack in protective packaging suitable for precision control modules.
- Global Logistics & Export Compliance – Classify under the correct HS code for industrial control modules. Packaging must protect against shock and electrostatic discharge; export documentation is prepared to minimize customs delays.
6. Technical Pitfalls & Integration Warnings
Configuration Matching – Feedback scaling, travel limits, dynamics, and demand transfer settings must match the original configuration. Incorrect settings can cause actuator instability or travel errors.
Feedback Devices – Confirm transducer type (single/dual, LVDT/RVDT/DC) and excitation requirements match the installed sensors.
DeviceNet Network – Verify node address, baud rate, and network power compatibility.
Actuator Current Range – Select the correct drive current range for the connected servo valve/coil. Exceeding or under-driving the coil can damage the actuator or degrade performance.
7. Frequently Asked Questions (FAQ)
What is the realistic global lead time for a verified 8200-226?
As a specialized Woodward servo controller, availability depends on surplus stock. Typical lead time after verification is 1–4 weeks plus standard shipping.
What is the primary function of this unit?
It is a servo position controller that positions a single-coil hydraulic or pneumatic actuator using DeviceNet or analog demand and position feedback.
What demand signals does it accept?
DeviceNet (primary) and 4–20 mA analog (backup or alternative primary).
What type of feedback does it support?
Single or dual position transducers (typically LVDT/RVDT or DC).
Does it replace earlier models?
Yes. It replaces the inactive models 8200-224 and 8200-225.
What should be confirmed before ordering a replacement?
Exact model and revision (8200-226), feedback device type, actuator current requirements, DeviceNet network settings, and the existing configuration parameters.
