Resistance to Position Converters for Electric Actuators

The Series 659 is a resistance to position converter which is typically located electrically between a retransmitting slidewire and an electric actuator. The primary application of the Series 659 is in tandem operation of electric actuators. Triac switching in the Series 659 drives the actuator through an angular direction corresponding to the position of the master control slidewire. A built-in potentiometer in the actuator, with wiper arm driven by the output shaft, provides a correctional feedback signal to the Series 659 to provide proportional action. The triac switching and feedback continues until balance is reached. Deadband, which is the difference between the input signal which will drive the motor one way and the level which will drive it the other way, is adjustable from 0.1% to 8% of the master control slidewire span. A deadband is recommended for less critical processes, since it will reduce mechanical wear on the actuator.
