Contact reinforcement by external contactors, 2-channel.
The output contacts can be reinforced by external contactors with
positively driven contacts for switching currents > 10 A. Functioning of
the external contactors is monitored by looping the NC contacts into the
closing circuit (terminals X1 - X2).
