ELECTRIC ACTUATOR POSITIONERS

Model SSC10-115/230V

A new electronic positioner provides accurate positioning control of electric motor actuators using an analog input signal.  Setup and calibration is greatly simplified using microprocessor based technology.  There are no dip switches to set or trim pots to adjust.  Setup is quick and easy using a menu viewed on an LED display.  No external meters are required, even for potentiometer setup.  Once the initial menu settings are chosen, the positioner performs a self-calibration routine, applying the menu selections to actual actuator performance.  Calibration values are then stored in permanent non-volatile memory.

Features

bulletOnboard LED display facilitates setup and calibration.
bulletMenu selection of input/output ranges including 4-20 ma., 1-5 VDC, 2-10 VDC and 0-10 VDC, or virtually any custom range required.
bulletAutomatic calibration;  no resistors to add; no jumpers, trim pots or dip switches to adjust.  Calibration is as simple as pressing a button.
bulletThree relay outputs; fault, full closed and full open. (A.C. Models Only.)
bulletCurrent sensing (over torque protection).  Optional on A.C. Models.  Standard on D.C. Models
bulletMenu selectable fail options.
bulletIntelligent positioning reduces motor cycling, increases motor life and extends the actuator duty.
bulletAuto-jog feature.  Constantly corrects and refines the positioning accuracy.
bulletAlways wires the same;   no need to determine rotation direction during installation;   rotation is selected using the menu.
bulletRobust power switching components, designed specifically for actuator motors, virtually eliminates field failures.
