Digital Indicators & Controllers>> Loop Powered Indicators
The ASHE Series 408 Digital Loop powered Indicators are compact, rugged and reliable indicating instruments designed for accurate measurement applications. The Indicator accepts an industrial standard current input signal of 4 to 20 mA DC and displays the process value calibrated to the desired units, on a linear scale. The process value is displayed on 4-digit or 4-1/2 digit seven-segment LCD and LED digital display modules. There is no necessity of any external Power Supply. The Indicator does not load the loop, having a nominal input impedance, and offers a forward voltage drop of 2.2 V DC at 20 mA DC current. Other features include automatic polarity detection, over-range detection, Zero and Span settings and fast response time.

The micro-controller based Digital Loop powered Indicator offers full calibration and decimal selection facility from the membrane keypad on the front panel. The Indicator is available in several dimensions in panel mounted execution and optionally in Weather-proof or Flame-proof executions. All ASHE instruments carry a lifetime warranty against defects in components and workmanship.
