SQM56.660R1Z3 Siemens Damper Motor

Overview

The Siemens SQM56.660R1Z3 is a high-precision reversing actuator designed for the accurate positioning of air and gas dampers, flow control valves, and butterfly valves. As part of the SQM5 series, this electromotive actuator is engineered for industrial and commercial burner applications that require a high degree of modulating accuracy and repeatability. The 660R1Z3 model features a “Z board” or multi-input option, allowing it to accept a wide range of control signals, and is configured for counterclockwise rotation without a factory-installed shaft, providing flexibility for custom field installations.

Features

• Multi-input “Z board” supports 4 to 20 mA, 0 to 135 Ohm, 0 to 10 Vdc, and 0 to 20 mA control signals
• Reversible synchronous motor with counterclockwise (CCW) factory configuration
• Internal auto/manual selector switch and manual forward/reverse toggle switch for simplified commissioning
• Disengagement clutches for the drive shaft and cam drum to allow for quick manual alignment
• Equipped with two limit switches and four internal auxiliary switches for complex control sequences
• Externally visible position indicator for easy monitoring of the rotation angle
• Durable construction with die-cast aluminum housing and impact-proof plastic covers
• Low hysteresis design ensures precise and stable positioning throughout its lifespan
