\n

An industrial power supply’s DC-OK contact is useful only when the control system can receive, interpret and act on it.<\/strong> Record the contact state, PLC input state and resulting machine action as separate events. Also establish how the record survives if the monitored supply powers the PLC itself.<\/p>\n

  1. Read the MDR-100-24 marking before designing the input<\/a><\/li>\n
  2. Follow the event through the complete control path<\/a><\/li>\n
  3. Budget the response without inventing a relay delay<\/a><\/li>\n
  4. Keep the test observable when control power disappears<\/a><\/li>\n
  5. Release the response record with the machine program<\/a><\/li>\n<\/ol>\n<\/details>\n

    This guide uses the WEHO MDR-100-24<\/strong> original product photograph to define an OEM response test. It addresses the path from a power-status indication to a documented control response, rather than treating the presence of an alarm terminal as proof that the equipment will stop or recover correctly.<\/p>\n
