The SQM5 Actuator

The Siemens 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.

The Siemens SQM5 is available in a wide range of torque ratings from 90 to 400 in-lbs with running times of 8 to 50 seconds. A selection of exchangeable circuit boards provides various functions, including zero and span adjustment, parallel or master/slave operation, split range control, input signal override, and selectable electronic linearization.
