AB | 1771-IL | Analog Input Module

Once an analog input signal is received, the 1771-IL converts the signal to 0000 to +409510 for unipolar ranges (0 to 5V, +1 to +5V, 0 to +20mA, and +4 to +20mA) and -409510 to 409510 for bipolar ranges +5V, +10V, +20mA input ranges. Unipolar refers to a value where counting start at Zero (0). Bipolar refers to a value wherein the maximum positive number has a negative complement. Basically, a unipolar number has no sign while a bipolar number has a sign. This module features 16-bit binary over full range resolution.
