The PC1001-A2 and PC1002-A2 Novigo Core digital audio matrix boards both
provide a dedicated potential free system fault relay connector. This connector lies
in the inputs/outputs area on the lower left side of the board.
The relay is activated in the regular operating mode. The relay is released in case
of a fault.
The relay contacts can switch a voltage of up to 48 V.
