The TS5100 Controller is a time/power source for the TS5000 Rotary Microvalve. Microprocessor based, it provides adjustable DC outputs from 6 to 24 volts, for motor drive. The digital time-set display shows motor on-time, both forward and reverse, from 1millisecond to 99.99 seconds. Motor activation is foot switch initiated, or can be tied to a machine actuated linit switch. An extra limit switch port is available to coordinate valve location in "Z" travel relative to dispense cycle initiation. Air adjustment for the syringe feed can be made from the unit's front panel.
