More Information

Overview Manuals Module Identity Obsolescence Notice Replacement Review Product Applications

Features:

  • Four actuator channels: retains the documented legacy channel arrangement.
  • 0–200 mA output range: supports the original actuator-control boundary.
  • Migration awareness: separates exact replacement from an engineered platform change.
This module is relevant when an installed Woodward control still uses the original four-channel actuator hardware and matching application.

A sound exact-part decision compares channel wiring, connector layout, revision and controller configuration before the outage begins.

Migration to newer hardware changes the engineering boundary and should proceed only with the required system and application modifications.

Apter Power supports exact-part review and legacy-spare quotation for Woodward 5464-544 4-Channel Actuator Module.
Woodward 5464-544 4-Channel Actuator Module Manuals,Datasheets,LinkImportant Notice: This linked Product Change Notification applies to 5464-544. Confirm the installed configuration before service.
  • Exact item: Retain the complete 5464-544 part number when reviewing an installed MicroNet module.
  • Module role: Woodward identifies 5464-544 as a four-channel actuator module.
  • Range boundary: The published module description identifies a 0–200 mA actuator range; it does not establish a substitute by itself.
  • Official notice: Woodward Product Change Notification 06924 lists 5464-544 within the affected four-channel actuator-module group.
  • Lifecycle event: The notice states that the older modules were scheduled for inactivation by 31 March 2015.
  • Service limit: Repair support in the notice was time-limited and dependent on component availability; do not treat it as a current service commitment.
  • Migration scope: Woodward directs users of the obsolete four-channel actuator family toward a two-channel actuator module or an SPC.
  • Engineering change: The same notice warns that these system changes require modifications to the GAP application software.
  • Approval boundary: A suggested product family is not a drop-in decision; assess the installed control configuration before authorizing a migration.
  • MicroNet context: Woodward groups 5464-544 with MicroNet four-channel actuator modules.
  • Actuator service: Its published 0–200 mA description defines the intended actuator-output range for the original module identity.
  • Legacy installations: Use it only where the installed record identifies this exact module and where a controlled repair or migration assessment has been completed.
Description
5464-544 is a Woodward four-channel actuator module with a documented 0–200 mA output range. It belongs to an older control-hardware generation and should be sourced by exact part number for an installed system.

The four outputs of 5464-544 tie the hardware decision to the existing terminal layout, actuator assignments and running application. Woodward migration guidance means that later actuator hardware is not a drop-in change and can require control-system modifications.

An outage involving 5464-544 should begin with an application backup, channel-wiring record and captured diagnostics. Proving every actuator loop through the approved site procedure protects the operating baseline before handover.
Technical notes
5464-544 is an obsolete Woodward four-channel 0–200 mA actuator module. Preserve application files, channel assignments, wiring and actuator data before removal; do not treat a later two-channel or SPC-based solution as a direct replacement without Woodward-qualified migration engineering. A mistaken direct swap can leave output loops or application logic unresolved.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Why does a migration request for 5464-544 need more than a like-for-like actuator-card quote?
Woodward classifies this item as an obsolete four-channel 0–200 mA actuator module and directs legacy replacements toward a two-channel actuator module or an SPC. Either route can require GAP application software changes, so it is an engineering migration decision.
When can 5464-544 remain the preferred choice for a running legacy MicroNet installation?
Where the installed application is already arranged around the original four 0–200 mA channels, an exact spare preserves that hardware identity. A different channel count or replacement architecture moves the work into controlled migration planning.
Can a two-channel actuator module be approved as a direct substitute for 5464-544?
No. Woodward lists a two-channel module as an updated path, but also states that system changes require GAP application software modifications. It must be evaluated as a system change, not approved as a direct swap.
How should a maintenance planner use the 31 March 2015 inactivation date for 5464-544?
Treat the date as a legacy-support boundary. Woodward offered a last-time-buy program for the old modules and described repair availability as component-dependent, so present availability must be confirmed rather than presumed.
What decision is required before moving 5464-544 actuator assignments to an SPC?
Decide whether the host application can be modified and validated. Woodward includes an SPC on the replacement path, but requires GAP application software changes; channel duties cannot be moved through parts-only substitution.
During a control-system upgrade, how does 5464-544 affect software scope?
Because Woodward ties either listed replacement route to GAP software modification, the module change belongs in the approved application revision and test scope. Hardware procurement alone does not complete the upgrade.
