Torque switching adjustable for directions OPEN and CLOSE Torque switching
Single switches (1 NC and 1 NO) for each direction, not galvanically isolated Standard:
Tandem switches (2 NC and 2 NO) for each direction, switches galvanically
isolated Options:
Potentiometer or 0/4 – 20 mA (EWG/RWG) Position feedback signal, ana-
logue (option)
Continuous indication, adjustable indicator disc with symbols OPEN and CLOSED Mechanical position indicator
(option)
