The new line of rotary stroke box actuators with integral analog control circuitry features a microprocessor based control circuit that accepts current, voltage, and resistance input signals. Calibration is field adjustable. Control overrides allow forcing the actuator to either end of travel on demand. Stroke lengths of 90¯ or 180¯ are switch selectable. Other stroke lengths can be set by adjusting the zero and span potentiometers. Direction of travel is also field selectable. The use of high temperature rated components, hobbed steel gears, die cast aluminum housing and the oil immersed motor and gear assures long term reliability.
