Information About SQM40.155R11
The SQM40.155R11 belongs to the Siemens SQM40 series of rotary actuators used in air and gas damper control systems. Its mechanical configuration is suited to applications requiring proportional positioning as well as compatible on/off control arrangements. The actuator uses screw terminals for electrical connections and incorporates a D-shaped shaft for mechanical coupling to the controlled device. The 4–20 mA input configuration allows integration with electronic control systems requiring modulating actuator operation.
Key Features:
- 4–20 mA Control: Accepts a 4–20 mA input signal for proportional actuator positioning.
- 110 V Operation: Designed for use with a 110 V AC power supply.
- 45 lb-in Torque: Provides approximately 45 lb-in of output torque for damper and valve positioning.
- 90° Rotation: Provides 90-degree counterclockwise rotation for controlled air and gas flow applications.
- 12.5-Second Timing: Completes the specified 90-degree rotation in approximately 12.5 seconds.
- 10 mm D Shaft: Uses a 10 mm D-shaped shaft for mechanical connection to compatible equipment.
- Form-C Auxiliary Switch: Includes a Form-C auxiliary switch for position-related control or feedback functions.
- Screw Terminals: Provides screw-terminal electrical connections for installation in compatible control systems.
The SQM40.155R11 delivers the reliability and precision required for proportional air and gas damper control applications.
