Electromechanical control unit
Counter gear mechanism for end positions CLOSED and OPEN
Standard: Single switches (1 NC and 1 NO; not galvanically isolated) for each end position
Options:
●
Tandem switches (2 NC and 2 NO) for each end position, switches galvanically isolated
●
Triple switches (3 NC and 3 NO) for each end position, switches galvanically isolated
●
Intermediate position switch (DUO limit switching), adjustable for any position
Limit switching
Torque switching adjustable for directions OPEN and CLOSE
Standard: Single switch (1 NC and 1 NO) for each direction, switches not galvanically isolated
Options: Tandem switches (2 NC and 2 NO) for each direction, switches galvanically isolated Torque switching
Potentiometer or 0/4 – 20 mA (RWG) Position feedback signal, ana-
logue (option)
Continuous indication, adjustable indicator disc with symbols OPEN and CLOSED Mechanical position indicator
