Woodward 5464-550 2-Channel Actuator Driver Module

Overview

The Woodward 5464-550 REV B, also cataloged as the 5464-550 2-Channel Actuator Driver Module, operates as a dedicated hardware component for actuator current signal execution within Woodward NetCon 5000 and MicroNet Control Systems.

Hardware Specifications

Actuator Loop Feedback Response

The Woodward 5464-550 uses an actuator driver architecture optimized for closed-loop positioning control. It receives digital system commands and converts them into proportional electrical output signals for electro-hydraulic, electro-pneumatic, and electric actuators.

The module maintains actuator loop feedback response by controlling output current stability and monitoring channel operation. In addition, the design supports precise valve positioning and speed/load regulation functions within governor and turbine control applications.

The module includes electrical isolation between control circuits and field actuator interfaces. Therefore, it reduces the influence of ground loops, external electrical noise, and field wiring disturbances on signal processing.

Frequently Asked Questions

Q: Does the Woodward 5464-550 support direct actuator connection without a control chassis?
A: No. The module requires installation in a compatible Woodward NetCon 5000 or MicroNet chassis and receives control commands through the system backplane.

Q: How many actuator outputs can the 5464-550 control simultaneously?
A: The module provides two independent actuator driver channels. Each channel processes separate actuator command signals.

Q: Does the module provide field signal isolation?
A: Yes. The 5464-550 includes onboard electrical isolation to separate control electronics from field actuator circuits and reduce interference effects.

Field Installation Guidelines

Install the Woodward 5464-550 in the designated chassis slot according to the NetCon 5000 or MicroNet hardware configuration requirements.

Verify that the backplane connector is fully seated before applying 24 VDC system power. Inspect the card guide alignment and front panel fastening screws to prevent mechanical movement during operation.

Use shielded field wiring for actuator connections where required by the installation environment. Connect cable shields according to the control system grounding practice and avoid routing actuator signal cables parallel to high-voltage power conductors.

Before commissioning, confirm actuator wiring polarity, output loop continuity, and system configuration parameters. Check the actuator feedback response during controlled operation to verify correct channel assignment.
