RHDE250 Electrical Rotary Actuator (Contrac)
Brand: ABB GroupCompact actuator for the operation of final control elements with rotary movement.
For continuous positioning, in explosion-proof design, rated torque 250 Nm (185 lbf-ft).
The actuator thrust rod transfers the force directly to the final control element.
Features- Electrical actuator for continuous positioning or step control
- Stallproof without the need of position or torque dependent switch off
- Explosion-proof design
- Three-phase asynchronous motor, hermetically sealed
- Connection areas with increased safety
- Sturdy gear unit with highly efficient design
- Adjustable mechanical limit stops for defined operating range
- Hand wheel for emergency operation
- Integrated sensors for position and temperature
- Signal and power input only via separate, microprocessor-controlled electronic unit
