      Information

      Overview Downloads Applications / Compatibility Product Precautions
      • Allen-Bradley 80026-044-02 serves a defined point in the MV SMC gate-drive power path. Separating the source, connections and monitored output helps locate the actual cause of a supply-related fault.
      Nominal input: 50 VDC
      Input diagnostic range: 50 VDC +/-8 VDC
      Isolated outputs: 6
      The IGDPS board provides continuous power to the gate-drive boards in applicable MV SMC optional stopping arrangements. Its six output circuits are isolated, with each channel identified at its output connection. Controller-specific wiring and quantity remain part of the installed assembly.

      The board is supplied from nominal 50 VDC. Each output module has a green indication for a healthy 20 VDC output; an extinguished indication corresponds to output below 18 VDC. If the group is dark, inspect the common input and connections before treating all channels as failed.

      The circuitry is epoxy encapsulated and has no internal field-test points or adjustments. The service test checks each accessible output at 20 VDC within +/-1%. A failed output requires replacement of the board rather than internal repair.
      Controller platform reference: MV SMC gate-drive power. Verify the installed supply and monitored connections.
      The original technical excerpt for Allen-Bradley 80026-044-02 covers exact supply identification and applicable fault investigation. The separate installation guide covers power-path identification, connection restoration and diagnostic comparison.
      Original manufacturer pages retain their technical context. Use the Apter Power guide with the applicable manufacturer instructions and approved installation design.
      System and supply context: 80026-044-02 requires its corresponding controller or drive assembly, retained wiring and matching auxiliary circuits. Connected loads and other supply stages are separate unless itemized.

      Application scope: Use the exact supply selection within the stated platform. Similar output voltages do not establish compatibility with a different source or gate-drive board.
      Prepare Allen-Bradley 80026-044-02 for its configured installation using these checks.
      Apply controller isolation

      Remove main and control energy using the approved MV SMC procedure and prove the circuits safe before touching boards, motor circuits or control devices.

      Protect encapsulated electronics

      Use appropriate ESD handling and support the board at its mechanical mounting. Do not open encapsulation or attempt internal adjustment.

      Restore channel assignments

      Reconnect each labeled output to its retained gate-drive position. Check seating and the common input connection without interchanging isolated circuits.

      Verify the common source

      Using the authorized safe test procedure, confirm the board input is 50 VDC +/-8 VDC. Resolve a missing common feed before investigating individual outputs.

      Measure every output

      Check pin 1 to pin 2 of each of the six outputs using the prescribed measurement arrangement. Compare each result with 20 VDC +/-1%.

      Compare LED and voltage

      All healthy channel indicators should be illuminated. Investigate a dark indicator, bad connection or low output; replace the board if an output module is defective.

      Alternative Names

      80026 044 02 Allen-Bradley 80026-044-02

      Technical notes

      Channel comparison: Measure the isolated outputs individually. One healthy channel does not establish that all six gate-power paths are available.

      Input-versus-output fault: If all channel indicators are dark, establish the common input condition before attributing the failure to six separate output modules.

      FAQ View All FAQ

      • How many isolated gate outputs does 80026-044-02 provide?
        Six isolated outputs supply the associated gate-drive circuits. Record the channel assignments before disconnecting them.
      • What input is expected when diagnosing 80026-044-02?
        The MV SMC diagnostic procedure expects nominal 50 VDC with an allowable check range of +/-8 VDC at the board input.
      • Why might every indicator on 80026-044-02 be dark?
        A missing input source or bad input connection can affect the whole board. Verify the common 50 VDC feed before diagnosing six independent output failures.
      • What does an extinguished channel LED on 80026-044-02 indicate?
        Its output voltage is below 18 VDC. Compare the indication with a controlled measurement and connection inspection.
      • Which voltage tolerance is used to verify the outputs of 80026-044-02?
        Each of the six outputs should measure 20 VDC within +/-1% under the prescribed test procedure.
      • Can a faulty output module inside 80026-044-02 be repaired in the field?
        No. The circuitry is encapsulated, with no internal test points or adjustments. A failed channel calls for board replacement.
      • Why is continuous gate power from 80026-044-02 needed for optional stopping modes?
        Applicable soft-stop and pump-control arrangements use the isolated supply to maintain gate-drive power rather than relying only on power derived from the operating snubber circuit.
      • How are multiple 80026-044-02 boards handled during a controller test?
        Test and record all six outputs on every installed board. One board passing does not establish the condition of other boards or their assigned gate circuits.
