Product Introduction
Woodward 8440-1546H Controller
The Woodward 8440-1546H is identified in repair-service records as an MSP Controller. It is associated with Woodward industrial control equipment, but the available documentation does not establish its exact control functions, electrical ratings, or interface configuration.
8440-1546H
The base number 8440-1546 is separately documented as an MFR-2 Multifunction Relay. Buyers should not assume that this base-number identification fully describes the H-suffix unit. Confirm the complete nameplate designation and hardware revision before selecting a replacement.
Application Scenarios & Field Pitfalls
Potential use should be determined from the original equipment documentation and cabinet wiring rather than inferred from the part number alone.
Engineering checks before replacement:
- Suffix verification: Confirm that the installed unit is specifically 8440-1546H, not 8440-1546 without the suffix.
- Configuration matching: Compare terminal assignments, firmware or configuration revision, and connected equipment requirements.
- Replacement validation: Do not treat a suggested replacement for the base 8440-1546 as a confirmed drop-in replacement for the H variant.
Related part reference: Woodward 8440-1936 is mentioned as a possible upgrade reference for the base 8440-1546, but the cited source describes a platform change rather than a form-fit-function replacement.
Please send a photo of the 8440-1546H nameplate or its front panel. That will help establish the exact product identity and avoid publishing incorrect technical specifications.
