Configurable outputs 1, 2, and 3, and triac binary outputs 8 and 9 are rated for a maximum current draw of 0.5 A. It is best practice to use pilot relays when you use these outputs to drive lighting contactors.
You can choose a pilot relay with a manual override function. You can also use software to reverse the polarity of the output. This means that you can drive contactors with contacts that are normally open (fail off) or normally closed (fail on).
