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.

The ASHE Model JM-408 Digital process Indicator is a compact, rugged and reliable indicating instrument which is specifically designed for accurate process measurement applications. The microcontroller based Indicator accepts an industrial standard current input signal of 4 to 20 mA DC and displays the actual process value calibrated in the desired units, on a linear scale. The process value is displayed on a 4-Digit seven-segment LCD or LED digital display module. There is no necessity of any external Power Supply.

The instrument can be calibrated on any scale range from -999 to +9999 units. The Ashe JM-408 Indicator is therefore an ideal single unit substitute to conventional analog indicators because of it's inherent accuracy in process control, besides other superior characteristics like total immunity to Shocks, Dust, Ambient temperatures, Humidity and Corrosive atmospheres. It's unique feature is that it is completely current loop-driven, eliminating the requirement of any external power supply source and associated cabling. Further, the instrument is manufactured using selected high-grade components which guarantee it's reliability and long operational life. The unit also has no moving parts, which greatly enhances it's versatility.
