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 monitoring 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!

24 - 240 V AC/DC, (drives can be operated with direct or alternating voltage)
Protection class:
IP 67 (version with actuating time 140 sec: IP 65)
Power-on time:
75%
Optional:
Regulating time 140 sec. (only for drive size 2, 85 - 240V AC/DC or special design 24V AC/DC: KH...ELI 24-140) -140, "Battery Safety Return" for emergency closing NC (default configuration) or emergency opening NO (conversion with a jumper) when there is a power failure -BSR, Positioning system 0 - 10 V or 4 - 20 mA (conversion with a jumper), precision: 3%, linearity: 2%, hysteresis: 3%, switch position NC or NO (conversion with a jumper) -DPS
Warning:
In case of high media temperatures, the actuator must be cooled if necessary!
