      Information

      Overview Manuals Common Applications Product Precautions
      In a DIOB-based event path, WESTINGHOUSE 7380A36G01 combines optical isolation, digital filtering, masking and synchronized time tagging. Contact resistance, common-return wiring and event-buffer handling must all be commissioned.
      • Sixteen contact inputs
      • 1/8 ms event resolution
      • On-card 48 V wetting
      • Dual event buffers

      Acceptance requires dry-contact simulation across all used points, confirmation of event timestamps and buffers, and verification of masking and common-return wiring.

      Important Notice: Isolate field contacts before handling WESTINGHOUSE 7380A36G01.

      1
      Isolate field contacts before handling WESTINGHOUSE 7380A36G01.
      2
      Confirm the full G01 identity and retain the installed DIOB address.
      3
      Record all sixteen point assignments, mask states and common-return wiring.
      4
      Keep closed-circuit resistance below the documented 60-ohm limit.
      5
      Maintain at least 50 kilohms leakage resistance for an open contact.
      6
      Verify the 48 V nominal wetting supply before evaluating field points.
      7
      Synchronize the QSE clock and test event-buffer transfer after startup.
      8
      Release the card only after every used input and its timestamp pass the event test.

      Technical notes
