Wiring the relay output

The SPC controller has one on-board 1A single pole changeover relay that can be assigned to any of the SPC system outputs. This relay output can switch a rated voltage of 30V DC (non-inductive load).

When the relay is activated the common terminal connection (COM) is switched from the Normally Closed terminal (NC) to the Normally Open terminal (NO).
