Applications
Single channel emergency-stop circuit without feed back loop, with or without automatic restart
Unless otherwise specified, the characteristics given are applicable to all or part of the product range selected

For automatic restart, terminals Y1 -
Y2 must be linked. No ON
-pushbutton necessary
For currents > 5 A, the output contacts can be reinforced by external contactors. Functioning of the external contactors is monitored by looping the NC contacts into the start circuit (Y1-Y2)
Applications
Contact reinforcement by external contactors
