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 recognizes 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 enhanced versions. The standard controller displays the pressure measured by a single active gauge. The enhanced controller supports two gauges, is equipped with two variable hysteresis set-points which are linked to 48V dc 1A changeover relays, and two 0-10V dc analog outputs. An RS232 interface is also available on the enhanced version.
