Reviewed by
  • Confirm the intended source voltage is present
  • Confirm common/reference is identified consistently
  • Confirm polarity-sensitive devices are oriented correctly
  • Confirm expected resistor values are installed
  • Confirm resistor wattage is appropriate for expected dissipation
  • Confirm no obvious shorts exist across the intended load
  • Confirm the circuit matches the latest drawing revision

If measured values differ materially from the expected values, stop and re-check the circuit before continuing.

Trust Boundary — Engineering Judgment Required

This site is an independent educational reference for industrial automation standards. It paraphrases and organizes guidance in original language; it is not a substitute for the official published standards, professional engineering judgment, or legal review, and content has not been independently verified against current published editions.

Items marked Review pending await technical review against the identified edition. Items marked Planned have no reviewed source material behind them. Do not rely on this site for compliance determinations, safety-critical design decisions, or legal interpretation.
