Description
The 88-PRO is a self powered display that operates using the loop signal to power the unit, with a voltage drop of 2.5V across the input terminals. Inputs available are 4-20mA, 10-50mA or 1-5mA loop signal and the display can be set with one or two fixed zeros, selectable via jumper switches, allowing a maximum reading of 19990 to 199900 to show on the display.
