Description
Foxboro IPM2-P0904HA | I/A Series Power Supply Module
Product Introduction
A replacement power module needs to match the installed system’s electrical requirements—not just its physical dimensions. The Foxboro IPM2-P0904HA is a legacy I/A Series power supply module identified in supplier records by its 39 VDC, 1.7 A output rating.
Also referenced as P0904HA, this module is associated with Foxboro/Invensys control-system hardware. Because it is a legacy component, buyers should verify the complete part number, input rating, output rating, and intended mounting/interface arrangement against the installed module before procurement. Do not substitute a different Foxboro power-supply model based solely on a similar product description.

Specification note: The 240 VAC / 0.4 A input and 39 VDC / 1.7 A output values are supported by part-specific supplier listings. Broader online descriptions contain conflicting or apparently unrelated specifications. Confirm the physical nameplate and applicable Foxboro documentation before applying electrical ratings.
Global Sourcing & Live-Test SOP
Power modules should be screened for correct identity, electrical condition, and suitability for the intended system. A visual inspection or seller title alone does not establish operating condition.
Incoming Verification
- Confirm the full IPM2-P0904HA model marking and P0904HA alternate reference.
- Record serial number, revision, and nameplate ratings where present.
- Inspect the housing, connectors, terminals, and accessible PCB areas for damage, corrosion, or evidence of repair.
- Photograph the nameplate and interfaces for procurement records.
Electrical & Configuration Review
- Match input and output ratings to the installed system documentation.
- Verify the intended mounting position and electrical interface.
- Check for any system-specific configuration or installation requirements.
- Confirm whether the module is supplied with required mating connectors or accessories.
Functional Test Procedure
- Use a qualified test setup appropriate for the module’s documented input and output requirements.
- Verify startup behavior and output voltage under suitable test conditions.
- Measure output stability under representative loads within the documented rating.
- Check for abnormal heating, noise, or intermittent output.
- Confirm compatibility in the intended Foxboro system where a suitable test environment is available.
Extended Run & Documentation
- Record test conditions, measured output, load applied, and test duration.
- Document any visible damage, repair history, or observed faults.
- Perform an extended run only when included in the seller’s test scope.
- Package using appropriate ESD protection and cushioning.
Testing transparency: This is a recommended inspection and acceptance procedure, not a claim that the specific IPM2- being offered has been tested. Request actual test evidence, condition details, and warranty terms from the seller.
Field Engineer’s Pitfall Guide
- ❗ Verify the output voltage before installation. Part-specific references identify the IPM2- as a 39 VDC, 1.7 A supply. Do not assume it is a 24 VDC or 5 VDC supply based on generic industrial power-module descriptions.
- ❗ Match the exact part number and interface.0904HA appear as related identifiers, but a similar Foxboro power module is not automatically interchangeable. Confirm the installed module’s complete marking and system documentation.
- ❗ Do not treat surplus condition as proof of electrical health. A module can appear clean and still have degraded output regulation or intermittent faults. For a critical control-system spare, request load-test results and confirm return or warranty terms before purchase.
Intent-Driven FAQ
Q1: What is the F?
It is a legacy Foxboro/Invensys I/A Series industrial power supply module.
Q2: What is the output rating ?
Part-specific supplier references list a 39 VDC output at 1.7 A.
Q3: What is the input rating?
Supplier references list 240 VAC at 0.4 A. Verify the actual unit nameplate and applicable system documentation before energizing.
Q4: Is the same part number?
is listed as an alternate part numb. Confirm the complete marking and revision when sourcing a replacement.
Q5: Can this module replace another Foxboro I/A Series power supply?
Only if the electrical ratings, interface, and system requirements match. Do not assume cross-compatibility based on the I/A Series designation alone.
Q6: still manufactured?
Surplus supplier records identify it as discontinued by the manufacturer. Confirm current OEM support and availability through the appropriate supplier channel.
Q7: Is the module tested or covered by a warranty?
That depends on the specific seller and unit. Verify test documentation, condition, warranty coverage, and return terms before purchase.
