Description
Product Introduction & Engineering Value
The Reliance 812.06.00 is a legacy Reliance Electric industrial-control part that should be treated as an exact-configuration replacement rather than a generic control board. Reliance systems used numerous hardware variants, and abbreviated catalog descriptions are often insufficient to establish electrical compatibility.
For maintenance procurement, the safest approach is to match the complete 812.06.00 identifier against the installed hardware and the equipment bill of materials. Confirm the host drive/controller, board revision, connectors, and application before purchasing. That prevents a physically similar legacy board from being installed in the wrong control architecture.

Important specification boundary
I am deliberately not inventing technical specifications for 812.06.00.
For industrial automation hardware, an incorrect voltage, signal type, drive family, or connector specification can result in a failed replacement or equipment damage. The correct technical data should come from the original Reliance documentation, equipment BOM, nameplate, or a verified physical sample.
Field Application & the “Trench” Experience
A legacy Reliance drive system develops an intermittent control fault. The maintenance team has the original schematic, but the board documentation is incomplete. The failed board is removed and sent for repair while production waits.
A replacement appears online under the same general Reliance product family. It looks close enough.
That is exactly when the purchase should stop.
For 812.06.00, the complete part number needs to be matched to the original equipment. On older Reliance systems, a small suffix or revision difference can represent a different electrical or functional configuration. An exact-match spare with documented testing is considerably easier to defend from an engineering standpoint.
Specific application scenarios
- Legacy DC drive maintenance — Replacement of control hardware in an established Reliance Electric drive cabinet.
- Industrial motor-control system — Maintaining an existing drive package where modernization has not yet been scheduled.
- Production-line drive repair — Keeping a critical spare available to reduce downtime from obsolete control hardware.

Transparency SOP: QA & Testing
Because public specifications for this particular part number are limited, testing should begin with identification rather than assumptions.
- Verify the label — Confirm Reliance 812.06.00 exactly.
- Record revision data — Photograph all labels, stickers, PCB markings, and revision codes.
- Inspect the hardware — Check connectors, PCB surfaces, components, mounting points, and signs of overheating.
- Compare physical configuration — Match the replacement against the failed board before installation.
- Identify the host system — Confirm the Reliance drive/controller in which the board is installed.
- Bench test where possible — Use the correct Reliance test environment rather than applying uncontrolled power.
- Functional verification — Verify the specific control function supported by the board.
- Document results — Record the test equipment, hardware revision, test conditions, and final status.
A supplier describing this part as “tested” should be asked what system it was tested in and what functions were verified.
The Veteran’s Tech Trap Guide
⚠️ Trap #1 — Guessing the function from the part number.
The designation 812.06.00 alone does not provide enough reliable public information to establish the exact electrical function. Do not build a purchase specification from an unverified marketplace description.
PRO TIP: Send the supplier a photograph of the original part and ask them to confirm the complete identification in writing.
⚠️ Trap #2 — Installing a similar-looking Reliance board.
Legacy Reliance hardware can have similar board layouts and connectors. Mechanical similarity does not establish electrical compatibility.
⚠️ Trap #3 — Skipping revision verification.
Record every visible revision and modification marking. A replacement with the same base part number may still require compatibility verification if the installed system contains a later hardware revision.
⚠️ Trap #4 — Accepting “power tested” as functional testing.
For a control board, successful power-up proves very little. The meaningful test is operation in a compatible Reliance system or an equivalent controlled test fixture.
Dynamic FAQ
What is Reliance 812.06.00?
812.06.00 is a legacy Reliance Electric industrial-control part. Publicly available information is not sufficient to responsibly assign a detailed functional description without additional identification data.
Which Reliance drive does 812.06.00 belong to?
The exact host drive/controller should be verified from the original equipment documentation or the physical board. I would not assign a specific Reliance drive family based solely on the part number.
Can another Reliance board replace 812.06.00?
Do not assume interchangeability. Confirm the complete part number, board revision, host drive, connectors, electrical characteristics, and control function.
What should I provide to identify it precisely?
The most useful information is a clear photograph of the front and rear of the board, especially the nameplate, PCB markings, connector labels, and any additional Reliance or Baldor identification numbers.
Is new-surplus stock acceptable?
Yes, if the supplier can establish that the actual unit is unused, correctly identified, properly stored, and electrically/ functionally tested as appropriate.
What warranty should I request?
For a legacy control board, request a written warranty covering functional operation after installation. Also confirm the supplier’s return procedure if the module fails commissioning.
