RHD250 Electrical Rotary Actuator
Brand: ABB GroupCompact actuator for the operation of final control elements with rotary movement.
For continuous positioning, rated torque 250 Nm (200 lbf-ft).
The actuator thrust rod transfers the force directly to the final control element.
Features- Process optimization thanks to maximum control precision
- Maintenance-free up to 10 years
- Electrical actuator for continuous positioning, three-point position control, or bus control
- Stallproof without the need for position- or torque-dependent shut-off
- Adjustable mechanical limit stops for defined operating range
- Handwheel for emergency operation
- Signal and power input only via separate, microprocessor-controlled electronic unit
