ABB Electrical rotary actuator RHD500 / RHD800 (Contrac)

Product Description

Compact actuator for the operation of final control elements with rotary movement. For continuous positioning, rated torque 500 / 800 Nm (400 / 600 lbf-ft). The actuator thrust rod transfers the force directly to the final control element.

General specifications:

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
