RHD250 Electrical Rotary Actuator

Brand: ABB Group

Compact 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
