Invert outputs - AXM Classic

A relay has two states:

  • Energised (coil energised)
  • Not energised (idle state)

The relay is normally in the idle state and is energised when an identification medium is activated.

The Invert SR signal checkbox changes the SmartRelay’s behaviour depending on the type of output (NO or changeover contact):
