Product detail:
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 circuit; 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. The internal 24-bit A/D conversion achieves a stable indication even at 4½ -digit resolution. For trend analysis, the measured signal is also be dis-played on a 41 segment bargraph. It’s possible to scale the bargraph separately. 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 its alarm limits. It is possible to configure the outputs as normal open or normal closed circuits. Additionally, the alarm limits appear graphically on a second bargraph. On one look you’re sure that the measured value is in its limits.
