SQM5...
Reversing Actuators
Description
Features
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.
