Ultra low-pressure pressure regulator MultiAir, MicroAir IV

for airspringtwo-stage

For Multilumen applications the MicroAir units are offered with up to four channels in a single stainless steel enclosure with one air inlet. Each channel has its own output, meter and controls so each lumen can be controlled separately. ULTRA LOW PRESSURE AIR CONTROLLER, MICROAIR IV, WITH 0-10 VOLT INPUT for controlling by PLC or other device and for high speed switching needed when making bump or taper tubing. The MicroAir IV accepts a logic input to select one of two set points. A zero to 10 VDC analog input to provide any pressure from near zero to full scale instantaneously. It can be connected to your PLC or any controller with the 0-10 volt input. With an added output option you can have closed-loop control. Operation: The MicroAir IV is connected to normal factory air. It regulates to the pressure set by a 0 to 10 volt input, or to one of the two manually set pressures by expelling surplus air. A precision voice-coil linear motor (no spring) with viscostatic damping ensures optimum speed and stability. OPERATIONAL MODES: Dual State mode – using logic signal to select which of two pressure set points is active. The Hi and Lo set points are adjusted with front panel knobs. Linear mode – A zero to 10 volt input controls pressure. Manual Setting– Set by turning the left side potentiometer only. Performance: The MicroAir IV responds to a step of 50% of full scale in less than 0.1 second (typically 20 msec) and maintains an accurate pressure at flow rates between zero and a maximum SCFH depending on the full scale range. Power: 110/220 VAC 50/60Hz Dual selectable voltage input 110 or 220 volts
