IME Model 108EL Loop Powered Digital Indicators allow the process variable from any 4-20 mA current source to be monitored in engineering units. Since the unit derives its power from the loop, no additional power supply or wiring is needed. Because of its low voltage drop (3.5 V at 20 mA), the model 108EL can be incorporated into almost any 2 wire loop, where local indication of a process variable is needed.

IME Model 108EL Indicators are designed for use in process industries where vibration, inclement weather and corrosive atmospheres prevail. The electronics are enclosed in a low cost UV resistant polycarbonate housing, which meets NEMA 4X and IP66/68 requirements.


  • 4-20 mA input, loop powered
