The OMDC-ASP10 is a compact, economical control that can be used with conventional AC, DC, or Brushless DC adjustable speed drive systems to provide an LED display of set speeds and precise, digital closed loop motor speed control. An on-board microprocessor with non-volatile memory coupled with sophisticated internal software makes the OMDC-ASP10 the ultimate in accuracy and control. Target speeds are displayed directly in RPM, FPM, GPM, process time, or any other engineering unit of measure. Friendly front-panel field programming permits customizing the controller to the exact specifications for each application; maximum and minimum set speed, decimal points or colon, operating mode (master or follower), and the constant which takes into account motor gear ratios. The OMDC-ASP10 is simple to operate… just set the desired RPM, rate, or

The OMDC-ASP20 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. 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
