Adtech Loop Powered Indicators


The Adtech LPI series of loop powered LCD indicators provide an ideal user-configurable solution for process indication. The units accept a process input signal of 4-20 mA DC and provide a 3 ½ digit, 7 segment 0.5” LCD display.

The 4-20 mA signal may be from a two-wire output loop or an output of three-wire or four-wire transmitters. Power is derived from the input signal with no external power source required. The 3 ½ digit LCD may display 4-20 mADC (4-19.99) or engineering units such as ºC or ºF, etc. The output may also be displayed as 0-100%. Zero and span controls are provided by two separate infinite resolution potentiometers. Jumpers are provided for decimal point position and display range
