Industrial Drive and Governor Control Properties

Operating within high-performance prime mover control systems, this unit relies on specialized actuator loop feedback response metrics to interface between electronic governors and hydraulic or pneumatic actuators with sub-millisecond latency. The board regulates internal power distribution to handle thermal heat sink dissipation profiles generated during high-load bipolar operations up to +/-250 mA. The internal digital processing architecture converts input demands via an 11-bit high-definition positioning matrix, eliminating calibration drift linked to component aging, and matches the driving profiles required by the Woodward 512 and 8256 series proportional actuators.

Frequently Asked Questions

Q: How does the 8200-226 module handle a sudden short-circuit condition within the external actuator coils?

A: The module relies on integrated hardware protection circuitry that immediately clamps the output loop to prevent damage, while concurrently registering a diagnostic fault signal back to the main electronic governor.

Q: Is the bipolar output current fixed, or can it be adjusted for smaller servo valves?

A: The output current is software configurable from +/-10 mA up to +/-250 mA, allowing engineers to calibrate the driver output to match the precise electrical parameters of the target actuator.

Q: What legacy Woodward modules does the 8200-226 directly replace?

A: This model serves as the official digital upgrade path for the legacy analog 8200-224 and 8200-225 driver boards.

Field Installation Guidelines

Mount the 8200-226 assembly securely inside the control enclosure, ensuring proper clearance around the integrated thermal heat sink structures to support unimpeded air dissipation. Before connecting the 18-32 VDC primary input power, verify that the power supply polarity matches the driver terminal block layout. Connect all analog demand signals (such as 4-20 mA or 1-5 VDC) and bipolar actuator drive loops using individual shielded twisted-pair cables. Terminate the shield drain wires at the designated enclosure chassis ground rail to prevent stray electromagnetic interference from degrading the 11-bit control resolution.
