General

The ADM 333 motorised actuator can move the connected final control element to any intermediate position. The integrated cut-off system with switching cams and micro-switches automatically switches off the actuator at the end positions.

The travel of the final control element is transferred via a torque limiter to the rotation angle of the potentiometer and is used for position feedback.

The retaining torque is ensured by the self-locking system.

Features

• Actuates final control elements such as butterfly valves and air dampers
• For controllers with a switching output (3-point)
• Synchronous motor with two limit switches and two auxiliary switches
• Feedback potentiometer with path shut-off
• Maintenance-free metal gearbox
• Positions the control unit to any intermediate position
• Three cable inlets with M16 × 1.5 cable gland for 4.5 to 10 mm cable diameter
