Siemens Combustion SQM50.464R1Z3 Reversing Actuator Damper Motor 110V 140lb-in Torque

Description:

Siemens SQM5 Reversing Actuator SQ5M...reversing actuators are used for the position of flow control valves, butterfly valves, dampers, or any application requiring rotary motion.  The SQM5 actuators accommodate control input signals of 4 to 20mA, 0 to 135, 0-10 VDC or 0-20 mA position proportional and floating control.  SQM5 actuators are available with up to six internal, easily adjustable switches. A selection of exchangeable circuit boards provide a variety of functions including auto/manual selector switch, manual forward/reverse toggle switch, zero and span adjustment, parallel or master/slave operation, split range control, input signal override, and selectable electronic linearization. The SQM5 is engineered for precision.  It is particularly well suited for applications requiring a high degree of modulating accuracy and repeatability. The SQM5 actuator may be mounted in any position.  A selection of mounting brackets and shafts provides installation felxibility and allows for the simple replacement of most compettitve actuators. Features: Two limit switches, plus up to four internal auxiliary switches Fully closed "economy position" switch Drive shaft and cam drum disengagement clutches Auto/manual switch, manual control forward/reverse toggle switch UL, CSA approved 24 and 110 Vac versions CE approved 220 VAC versions Field reversible clockwise (cw) or counterclockwise (ccw) operation Various torque ratings and running times available Selection of field exhangeable single-ended and dual-ended shafts Mounting brackets to replace competitive actuators Connections for both base and face mounting Low hysteresis actuator and potentiometer gearing Externally visible position indication Selection of input and output signals Zero and span adjustment Field exchangeable circuit boards and potentiometers Electronic damper linearization function Split range and selectable parallel or master/slave operation Adjustable input signal override function
