Reversing Actuators
Siemens Building Technologies, Inc.
Description
SQM5... reversing actuators are used for the positioning of flow control valves, butterfly
valves, dampers, or any application requiring rotary motion. The SQM5… actuators
accommodate control input signals of 4 to 20 mA, 0 to 135 , 0 to 10 Vdc, 0 to 20 mA,
position proportional and floating control. The available output signals include
4 to 20 mA, 0 to 135 , 0 to 10 Vdc, 0 to 20 mA, and 0 to 1000 . 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 flexibility and allows for the simple replacement
of most competitive 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 exchangeable single-ended and dual-ended shafts
 Mounting brackets to replace competitive actuators
