Before you choose

What Should You Check Before Buying?

Use these relays requirements to narrow your shortlist, then verify each requirement for the exact model.

  1. Distinguish dry-contact and powered-output requirements.
  2. Verify load ratings for the actual load type, not only resistive loads.
  3. Check channel count, enclosure space and wiring instructions.
  4. Confirm local input behavior and recovery after a power interruption.
