Description
Product Introduction & Engineering Value
The DS3815 family sits alongside the DS3800 hardware commonly encountered in older GE Mark IV installations. The important procurement point here is the complete DS3815P0PA1A designation. Do not substitute another DS3815 board merely because the physical dimensions or connector layout appear similar.
Public parts listings confirm that DS3815P0PA1A is a separately identified GE component. However, I would not assign an unverified I/O count, voltage rating, signal type, or specific circuit function to this exact board based only on reseller catalogs.

Specification caution
I would not publish specific voltage, current, I/O, connector, memory, or communication specifications for DS3815P0PA1A without the GE drawing or an authoritative technical reference. The available search results establish the part’s identity but do not provide enough evidence for those parameters. This is preferable to carrying an incorrect specification onto a procurement page.
Field Application & the “Trench” Experience
A turbine site running a legacy Mark IV system reaches a planned outage with one DS3815 board already flagged as a potential spare requirement. The maintenance team finds several GE boards in the storeroom, but only one carries the complete DS3815P0PA1A designation.
The technician photographs the original PCB, records its cabinet position, documents every connector, and compares the board markings against the spare. No assumptions are made from the DS3815 prefix alone. The replacement is then electrically inspected before installation.
That is the right procedure for obsolete control hardware. When documentation is thin, physical identification and configuration traceability become part of the engineering verification process.
Niche application scenarios:
- GE Mark IV turbine-control cabinet maintenance
- Legacy Speedtronic board-level troubleshooting
- Planned turbine outage spare replacement
- Obsolescence management for DS3815 control hardware

Transparency SOP: QA & Testing
For DS3815P0PA1A, a credible supplier should be able to document the following:
1. Part-number verification
Confirm the exact marking on the actual PCB.
2. Physical inspection
Check PCB traces, solder joints, connectors, components, mounting hardware, corrosion, contamination, and evidence of previous repair.
3. Configuration comparison
Compare the spare against the customer’s installed board. Photograph both sides when possible.
4. Electrical testing
Use an appropriate GE Mark IV/DS3815 test procedure when available. Generic continuity testing should not be presented as a complete functional test.
5. Final QA record
Document the actual unit tested, condition, test status, photographs, and material classification.
This distinction is especially important because currently indexed market inventory includes . One recent listing identified the item as used and stated a two-year Radwell warranty, but that warranty is supplier-specific rather than an OEM GE warranty.
The Veteran’s Tech Trap Guide
⚠️ Trap #1 — Don’t infer the function from the part number.
Public information for this exact DS3815 variant is sparse. Avoid assigning a specific control function unless the site’s GE documentation confirms it.
⚠️ Trap #2 — Match the complete configuration.
is not the same procurement identifier as DS3815PAAA, DS3815PCBA, DS3815PFPA, or another DS3815-series board. The broader DS3815 family contains multiple distinct boards.
⚠️ Trap #3 — Used does not mean tested.
A used PCB can have an excellent appearance and still contain aged capacitors, intermittent connectors, or previous repair work. Ask exactly what was tested.
PRO TIP: For this particular part, request a photograph showing the complete board identification, not merely a generic DS3815 product photograph.
Dynamic FAQ
Q: What is the GE DS3815P0PA1A?
A: It is a GE DS3815-series Mark IV turbine-control PCB. Public sources confirm the exact GE part number, although detailed circuit-level specifications are not readily documented in current public references.
Q: Is DS3815P0PA1A interchangeable with another DS3815 board?
A: No. The complete configuration must be verified against the installed board and GE system documentation.
Q: What specifications should I verify before ordering?
A: Confirm the board function, connector configuration, electrical ratings, cabinet position, revision/configuration markings, and applicable GE drawing or manual.
Q: How should New Surplus authenticity be checked?
A: Request photographs of the actual unit, confirmation that it has never been installed or energized, and the supplier’s inspection/testing documentation.
Q: What should I request for a Refurbished unit?
A: Ask for the refurbishment scope, replaced components if applicable, functional-test procedure, actual-unit photographs, and written warranty terms.
Q: Is there a warranty available?
A: Warranty coverage depends on the supplier and material condition. For example, a recent Radwell listing for a used DS3815P0PA1A stated a two-year Radwell warranty. That is a reseller warranty, not a GE OEM warranty.
