General Information

          The digital Indicator D122 indicates measured values of intrinsically safe current circuits from 4 up to 20 mA in hazardous areas. The device is powered by measure current, therefore an extra power supply or batteries are unnecessary. The indicator measures the current, scales the measured value and displays finally the result on the LCD.

          For trend analysis, the measured signal is also be displayed on a 41 segment bargraph. It’s possible to scale the bargraph separately to the digital value. The indicator D122 is available in several housings.

          Furthermore with alarm monitoring option the indicator has two intrinsically safe alarm outputs. These outputs change their state, when the measured value exceeds his alarm limits. It’s possible to choose open-circuit or closed-circuit connection. These options are not allowed in Zone 21 and 22.

          Additional the alarm limits appear graphically on a second bargraph. On one look you’re sure that the measured value is in its limits
