The Accu-Set II Series digital control unit, with an advanced 16-bit Microprocessor, is designed for use with conventional AC frequency or DC drives, any horsepower, to provide: LED display of set or actual speed, closed loop motor speed control, Master or Follower modes, and Serial communications. The Accu-Set II Series is a companion control to the Accu-Set Series, while offering significantly improved performance. This control features a true P-I-D algorithm, for extremely responsive and precise control over a wide variety of desired speeds and applications. Set or actual speed is displayed directly in RPM, FPM, Process Time, or other engineering units. Field programming permits customizing specific operating parameters. The integrated RS485/RS422/RS232 serial interface port is perfect for monitoring or control using almost any computer or process controller. Units can even be attached in a Local Area Network, and can then be controlled and programmed either individually or all at once. Multiple programs allow the user to choose between a “menu” of up to six programmed configurations. The Accu-Set II Series is ideally suited for commercial or industrial applications, including system up-grades.

These closed loop devices require an encoder / speed pick-up. The Dart PU-E is an excellent choice!
