Rotary actuator
Description:
Electrical rotary actuator with optical position indicator, manual emergency operation and switch room heating Two additional limit switches are installed for further control requirements. An electronic torque limiting unit prevents damage in the event of overload. The manual emergency operation can be done without dismantling the external cladding. Do not use upside down!
Materials:
housing: PA 6
Temperature range:
-20°C do +70°C
Voltage:
24 - 240 V AC / 24 - 135 V DC, (actuators can be powered with AC or DC voltage).
Protection class:
IP 67
Power-on time:
75%
Optional:
"Battery Safety Return" for emergency closing NC (standard configuration) or emergency opening NO (conversion with a jumper) when there is a power failure -BSR
Warning:
In case of high media temperatures, the actuator must be cooled if necessary!
