SQM56.664R1Z3 Siemens Damper Motor

Overview

The Siemens SQM56.664R1Z3 is a high-precision reversing actuator designed for the accurate positioning of dampers, butterfly valves, and flow control valves. Engineered for industrial and commercial burner applications, this motor is particularly well-suited for systems requiring exceptional modulating accuracy and repeatability. It features a robust design capable of mounting in any position and includes exchangeable circuit boards that allow for a wide range of control functions and signal integration.

Features

• Self-contained reversing actuator providing precise rotary motion
• Equipped with two limit switches and four internal auxiliary switches for flexible control logic
• Includes an auto/manual selector switch and a manual forward/reverse toggle switch for easy field adjustments
• Features exchangeable circuit boards for functions like zero and span adjustment and electronic linearization
• Low hysteresis design with a double-offset drive and potentiometer gearing for stable performance
• Externally visible shaft position indicator for quick status monitoring
• Field reversible operation for clockwise or counterclockwise rotation
