Siemens Combustion SQM40.241R11 Actuator 110V 4-20mA 135 Ohm Control CCW

The Siemens Combustion SQM40.241R11 Actuator is designed for the accurate modulation control of HVAC burners and dampers for demanding combustion applications. It has an input current control of 4-20mA to rotate in the counterclockwise direction over 90 degrees. The actuator moves depending on the current received and provides accurate mechanical movement by using a 135 Ohm feedback resistor. Suitable for industrial furnace applications and commercial HVAC burner assemblies, this 110V actuator can provide better energy saving, fuel saving, combustion stability, and safe operation with positioning and response rate.
