4 Connecting the modules → Q.bloxx A101: Connecting sensors and I/O
Voltages which exceed the admissible limits produce incorrect
measurement data, because the inputs are protected against
overvoltages and limit the input voltage.
Fig. 4-19 A101, measurement of voltage.
4.8.2 Current
A shunt resistance of 50 is integrated into the Q.bloxx Module
A101 for current measurement. This facilitates the measurement
of currents of up to 25 mA. For higher currents use a voltage mea-
surement and an external shunt; refer to Section 6.5, page 147.
Fig. 4-20 A101, measurement of current.
4.8.3 Potentiometer
Potentiometers with resistances between 1 k and 10 k are con-
nected in a three-wire configuration.

4.8.4 Resistance, Pt100, Pt1000
You can connect resistances and Pt100/1000 probes in two-wire
or four-wire circuits. You specify the selected type of circuit
during the module configuration (Type column).
