ADC Enhanced
Active Digital Controllers


The Edwards Active Digital Controller (ADC) is a compact single gauge controller and display.
It features a bright LED display and simple push-button controls.
The ADC automatically recognises compatible Edwards gauges, loads the appropriate look-up table and displays the pressure in commonly used vacuum units.
Two versions are available; the standard ADC simply displays the pressure in choice of units, and the enhanced ADC includes a second gauge connection, two set-point relays, two analogue outputs and an RS232 interface. The ADC mk2 enhanced controller can now support 2 different gauges, e.g. APG100 and AIM.

Features and Benefits
• Plug and measure operation means you simply plug in the mains supply, connect the gauge and ADC displays the
measured pressure.
• The ADC supports Edwards gauges with a total measuring range of 2000 to 1 x 10⁻⁹ mbar (1500 to 7.5 x 10⁻¹⁰ Torr).
• Bright LED display gives clear, long distance readability.
• The ADC displays units in mbar, Torr, Pascal or Volts.
• Small 1/8 DIN enclosure, may be panel or bench mounted.
• Simple push-button control makes operation highly intuitive.
