ADC Compact Gauge Controller/ Display
Active Digital Controller
Overview
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 enhanced controller supports two similar gauges - it has two variable hysteresis set-points which are linked to 48 V d.c. 1 A 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 a suitable gauge, such as the Edwards APGX H 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.

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 hich are linked to 48 V dc 1A changeover relays and two 0-10 V dc analog outputs. To aid system integration the enhanced ontroller is provided with an RS232 interface.
