Measuring ranges of the analog input modules in SIMATIC S7 format for voltage,
current and resistance-type sensors
Introduction
The following tables contain the digitized analog values for the measuring ranges of the
analog input modules.
Since the binary representation of the analog values is always the same, these tables
contain only a comparison of the measuring ranges with the units.
Voltage measuring ranges: ± 80 mV, ± 2.5 V, ± 5 V, ± 10 V
