Description
Product Overview
The Woodward 3522-1004 is identified in Woodward’s EM-80/EM-300 actuator-system documentation as an electric actuator driver. It forms part of a closed-loop actuation system used in prime-mover control applications, where an electronic demand signal is converted into controlled actuator movement. Depending on the machine design, the system can be used for fuel-control mechanisms and other approved engine or turbine positioning applications. Woodward’s official Manual 26761 covers the EM-80/EM-300 actuator system, installation precautions, and replacement considerations.
The driver works with a compatible actuator and position-feedback arrangement. Published system specifications list a three-phase 400–480 V AC supply, 4–20 mA or 1–5 V control input, and a 0–5 V position output. The equipment is designed for cabinet installation, with protective-earth grounding and appropriate electrical safeguards required. These are driver-level specifications and should not be confused with the actuator’s mechanical output ratings or the voltage indicated by the 12/24 portion of the separate BUM60 designation.
For procurement, the combined identifier BUM60-12/24-54-B-001 / 3522-1004 needs careful verification. Search results also associate the BUM60 designation with Baumüller servo-drive equipment, while Woodward documentation identifies 3522-1004 as an EM actuator driver. The two identifiers should not be assumed to describe one interchangeable module or a power-buffer unit without checking the physical label and system bill of materials. Confirm the full Woodward part number, serial number, revision, and applicable actuator model before ordering.
Product Introduction
The Woodward 3522-1004 is an EM-80/EM-300 electric actuator driver used in compatible engine and turbine control systems. It provides the electrical drive and control interface needed to operate an associated actuator under closed-loop position control.
When sourcing equipment listed as BUM60-12/24-54-B-001, verify the exact hardware identity and system pairing first. Use the applicable Woodward documentation to confirm electrical requirements, wiring, and replacement procedures.

Frequently Asked Questions
Q1: Is 3522-1004 a power-buffer module?
Woodward’s EM-80/EM-300 documentation identifies 3522-1004 as an actuator driver. Some reseller descriptions classify it differently, so verify the unit label and manual before specifying it as a buffer module.
Q2: Can the driver be hot-swapped?
Do not assume hot-swap capability. The driver uses a high-voltage three-phase supply and can cause actuator movement when energized. Isolate power, follow lockout procedures, and secure the controlled mechanism before maintenance.
Q3: Does the driver require configuration?
The complete actuator system may require application-specific control and feedback settings. Preserve the existing configuration where possible and follow the documented commissioning process for the exact driver revision.
Q4: Can 3522-1004 replace 3522-1042?
Not as an assumed direct substitution. Woodward references a conversion procedure for upgrading earlier drivers, including 3522-1004, to newer versions such as 3522-1042. Check the applicable conversion documentation before replacement.
Q5: What electrical supply does the driver require?
The published specification lists three-phase 400–480 V AC at 50–60 Hz. Verify the actual nameplate and cabinet supply before installation. Do not infer the driver’s AC input from the 12/24 code in the designation.
Q6: How should the buyer verify condition?
Request photographs of the complete nameplate, part number, serial number, connectors, and enclosure. Ask for functional-test or repair records and confirm whether the unit is new, used, repaired, or refurbished.
Q7: What should be checked before commissioning?
Verify protective-earth grounding, supply voltage and phase, cable shielding, actuator-feedback wiring, control-signal scaling, and all machine-level safety functions. Woodward specifically warns that actuator movement may occur when power is first applied, so commissioning must follow the documented safety procedure.
