Siemens Combustion Control SQM56.664R1Z3 Reversing Damper Actuator in-lbs - 120V 400

The Siemens SQM56.664R1Z3 is a heavy-duty reversing damper actuator designed for combustion control applications, featuring 400 in-lbs of torque with a 50-second travel time for 90-degree rotation. This multi-input actuator operates on 120VAC and features a 3/8-inch square shaft with counter-clockwise rotation.

Key Features:

• Ultra-high torque (400 in-lbs) with reversing capability
• Multi-input capability accommodates 4-20mA, 0-135 ohms, 0-10 VDC, and 0-20 mA control signals
• Available with up to six internal, easily adjustable switches
• 50-second travel time for smooth, precise positioning
• Integrated 3/8-inch square shaft for direct mounting
• Exchangeable circuit boards provide functions including zero and span adjustment, parallel or master/slave operation, and split range control

SQM5 reversing actuators are used for the positioning of flow control valves, butterfly valves, dampers, or any application requiring rotary motion. In commercial and industrial burner applications requiring high turndown and reliable ignition, the auxiliary switches can be applied to create separate positions for burner ignition and low fire, and in dual fuel applications, additional switches can be used to create separate high fire, low fire and ignition positions for each fuel. The SQM5 actuator may be mounted in any position, providing flexible installation options.

Siemens Combustion control valves and actuators are approved for use worldwide. The SQM5 is engineered for precision and is particularly well suited for applications requiring a high degree of modulating accuracy and repeatability.
