Volts Measurement Type (VOLT Jumper Setting)
Voltage measurement involves applying voltage across the Base Plate input
terminals (10-11 or 12-13), making sure to note the correct polarity, setting the
gain accordingly, and then reading the voltage. The input resistance of the AI-
10 in voltage mode is 7,246
Ω
± 0.3%, and the attached sensor must be able to
drive that load in order to obtain consistent results.
Based on the gain setting, the input ranges available are shown in the following
table:
AI-10 Analog Input Module Gain Setting and Voltage Range
Gain Setting Voltage Range
x1 0 - 20V
x2 0 - 10V
x32 0 - 625mV
x128 0 - 156mV
