L/S Computer-Compatible Digital Drives 

Interface this digital drive to a PC for automated lab and process applications--or use as a stand-alone dispensing pump

• Precision digital drive offers a maintenance-free high-accuracy motor and an all-new graphical interface that makes setup and operation easier than ever
• Graphical LCD shows four operating modes continuous run, timed dispense, copy dispense, volume dispense. View pump performance continually.
• Menu-driven interface lets you select one of seven languages for programming and operation
• Dispense by mL—volume in mL of each dispense, 0.001 to 9999 mL; Copy—1 to 9,999 dispense cycles; or SEC—time interval between each dispense cycle (1 sec to 99 hr, 59 min, 59 sec)
• Brushless, maintenance-free motor offers ±0.1% speed control accuracy with a 6000 to 1 turndown ratio
• Remote control via DB25 female connector on drive:
  --Speed control input 0 to 20 mA, 4 to 20 mA, or 0 to 10 V;
  --Pumping direction requires open collector or contact closure;
  --Start/stop/purge requires open collector or contact closure;
  --Tachometer output 0 to 20 mA, 4 to 20 mA, or 0 to 10 V, open collector

This precision drive offers analog remote control options and simple programming—ideal for automated process applications. The drive feature a programmable dispense interval that lets you set the delay between dispense cycles for convenient, automated dispensing. Programmed calibration ensures dispense and display accuracy—drive stores one calibration value per tubing size.
Program the drive via the simple membrane keypad; keypad lock/unlock feature protects settings. Motor is reversible so you can purge tubing before or after pumping and pump fluid in either direction.
