TIPL Loop Powered Indicator IT57.DI accepts 4-20 mA or 10-50 mA process loop signal and indicates process variables in percent or in engineering units such as pressure, flow, temperature and level on digital display. No separate power is required as it takes power directly from current loop with a voltage drop of 3.2V max. The indicator has full zero and span scaling capability for any desired engineering unit display in five DIP switch selectable ranges and three DIP switch selectable decimal points. Fine zero and span settings can be done by 20 turn trimmer Potentiometers. The indicator is housed in weather proof IP85 housing suitable for pipe and surface mounting. The indicator is also available in DIN-RAIL panel mount type housing. TYPICAL CONNECTION
