Contact reinforcement by external contactors, 2-channel controlled.
The output contacts can be reinforced by external contactors with forcibly
guided contacts for switching currents > 8 A.
Functioning of the external contactors is monitored by looping the NC
contacts into the closing circuit (terminals S33-S34).
Note: Refer to „Unit programming“!
