Product Description
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 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 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.
Features and Benefits
- Plug and measure operation means you simply plug in the mains supply, connect the gauge and ADC displays the measured pressure
- The 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
- Bright LED display gives clear, long distance readability
- The ADC displays units in mbar, Torr, Pascal or Volts
- Small 1/8 DIN enclosure, may be panel or bench mounted
- Simple push-button control makes operation highly intuitive
