Refer to actuator name plate
Output speed
Standard: 3-ph AC asynchronous motor, type IM B9 according to IEC 60034
Motor
Standard: F, tropicalized
Option: H, tropicalized
Insulation class
Standard: PTC thermistors (according to DIN 44082)
Option: Thermoswitches (NC)
Motor protection
Self-locking: Output speeds up to 90 rpm (50 Hz), 108 rpm (60 Hz)
NOT self-locking: Output speeds up to 125 rpm (50 Hz), 150 rpm (60 Hz)
Multi-turn actuators are self-locking, if the valve position cannot be changed from standstill
while torque acts upon the output drive.
Self-locking
Counter gear mechanism for end positions CLOSED and OPEN
Turns per stroke: 1 to 500 (standard) or 1 to 5,000 (option)
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 switches (1 NC and 1 NO; not galvanically isolated) for each direction
Option:
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-
