Single channel emergency-stop circuit without feed back loop, with or without automatic restart

Single channel emergency-stop circuit without feed back loop, with or without automatic restart
For automatic restart, terminals Y1 - Y2 must be linked. No ON-pushbutton necessary

Contact reinforcement by external contactors

Contact reinforcement by external contactors
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)
