Because each of the two groups has its own common (VAC\/VDC COM), you can simultaneously control a 120V AC lighting circuit on Group 0 and a 24V DC hydraulic valve on Group 1.

To ensure long-term reliability of the relay contacts when switching inductive loads (such as motor starter coils or solenoids), it is highly recommended to install external surge suppression.
