This Active Digital Controller (ADC) is a compact single gauge controller with automatic recognizes compatible Edwards gauges, loads the appropriate look-up table and displays the pressure in commonly used vacuum units.

• Bright LED display gives clear, long distance readability
• The ADC displays units in mbar, Torr, Pascal or Volts
• Simple push-button control makes operation highly intuitive
• This gauges are mainly used in laboratory and industrial applications

The enhanced controller supports two similar gauges - it has two variable hysteresis set-points which are linked to 48 V DC. 1 A changeover relays and two 0 to 10 V DC analog outputs. To aid system integration, the enhanced controller is provided with an RS232 interface. When combined with a suitable gauge, such as the Edwards APGXH Convection Pirani or Wide Range Gauge (WRG), the ADC represents a cost effective means of monitoring and controlling process vacuum in a broad range of applications.
