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 Ω, 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 Ω, 0 to 10 Vdc, 0 to 20 mA, and 0 to 1000 Ω. 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. Drive shaft play is
limited to 0.3° with a modulating accuracy of 250 repositions through 90° of travel.
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.
