SQM56.684R1Z3 Siemens Damper Motor

Overview

The Siemens SQM56.684R1Z3 is a high-performance modulating reversing actuator designed for the precise positioning of air dampers, gas flow control valves, and oil volume regulators in medium to large capacity industrial burners. Engineered for high-demand applications, this actuator provides exceptional modulating accuracy and repeatability. It features a robust die-cast aluminum housing and is equipped with an internal electronic circuit board that allows for versatile control integration, including multiple input and feedback signal options.

Features

• High torque output of 400 in-lbs (40 Nm) for handling large dampers and valves
• Equipped with eight internal switches including two limit switches and six auxiliary switches
• Modular design with exchangeable circuit boards and potentiometers for field flexibility
• Integrated auto/manual selector switch and manual forward/reverse toggle switch for easy adjustments
• Field-reversible rotation allowing for both clockwise and counterclockwise operation
• Externally visible position indicator for at-a-glance monitoring
• Drive shaft and camshaft can be disengaged separately for simplified setup
