EM with analog inputs
By means of expansion modules with analog inputs, continuously changing
signals, such as those that occur when measuring temperature or pressure, can be
recorded, evaluated and converted to digital values for further processing.
Features of the analog inputs
The expansion modules with analog inputs have the following features:
Different measuring ranges:
– 10 V
– 20 mA, 4 to 20 mA (four-wire measuring transducer, parameterizable)
– 4 to 20-wire measuring transducer)
– Pt100 resistance thermometer (two-, three- or four-conductor connection
possible)
SIMATIC S7 and SIMATIC S5 data format (parameterizable)
Resolution of 12 bits plus sign
2 channels (same measuring range and data format for both channels of an
expansion module)
24 VDC supply voltage for expansion module and sensor via backplane bus
Analog inputs not isolated from the internal electronic components
Integration time 16.7 ms/20 ms (parameterizable)
