Active Digital Controller, ADC MkII Enhanced
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.
