System compatibility

DSA-022-460-S belongs to DANAHER MOTION DSA servo actuator family. Compatible with mainstream analog motion controllers and PLC systems. Designed for industrial automation, HVAC and process control applications. Used to drive air dampers and control valves.

Function

DSA-022-460-S is rotary servo actuator manufactured by DANAHER MOTION. It receives 4-20mA positioning command signal from controller and rotates output shaft to target angle. Built-in position feedback transducer sends actual shaft position back to controller for closed-loop control. The handwheel allows manual operation for stroke setting and maintenance. It adjusts damper or valve to maintain accurate positioning for process control applications.

Installation

Follow lockout/tagout safety procedure before installation. Mount DSA-022-460-S on machine or valve frame. Connect mechanical linkage to damper or valve shaft. Wire 24VAC power and 4-20mA command/feedback cables strictly follow DANAHER MOTION DSA series wiring manual. Perform full stroke calibration and linkage test during commissioning.

Interface

0.22" output shaft,24VAC power terminals,4-20mA command input,4-20mA position feedback,manual handwheel,aluminum actuator housing for DANAHER MOTION DSA-022-460-S.
