PRODUCT DATA SHEET ACTIVE DIGITAL CONTROLLER (ADC) Edwards Active Digital Controller (ADC) is a compact single line vacuum gauge controller and display, featuring 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. The ADC is available in standard and MkII enhanced versions. The ADC standard controller displays the pressure measured by a single active gauge. The MkII enhanced controller now supports two different gauges with two variable hysteresis set-points which are linked to 48 V d.c. 1A changeover relays and two 0-10 V d.c. analog outputs. To aid system integration the enhanced controller is provided with an RS232 interface. When combined with suitable gauges such as the Edwards APG100 Pirani, AIM Inverted Magnetron or Wide Range Gauge (WRG), the ADC represents a cost effective means of monitoring and controlling process vacuum in a broad range of applications. Features and benefits • Plug and Go operation ͵͵ Simply plug in the mains supply, connect the gauge and the ADC displays the measured pressure • Wide pressure range ͵͵ 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) ͵͵ ADC and Edwards gauges address a broad spectrum of laboratory and industrial applications • New multiple gauge ability ͵͵ The new enhanced ADC MkII can now support two different gauges making it a more versatile instrument controller • High visibility display ͵͵ Bright LED display gives clear long distance readability • Choice of units ͵͵ ADC displays in mbar, Torr, Pascal or Volts • Compact instrument ͵͵ Small 1/8 DIN enclosure, may be panel or bench mounted • Very simple to use ͵͵ Push-button control makes
