Q.seriesGantner Instruments Test & Measurement GmbH 434 Connection → Q.brixx A107: Connecting sensors4.10.2 CurrentA shunt resistance of 50 is integrated into the Q.brixx ModuleA107 for current measurement. This facilitates the measurementof currents of up to 25 mA. For higher currents use a voltage mea-surement and an external shunt; refer to Section 6.4, Page 101.Fig. 4-39 A107, measurement of current; left: terminal version;right: D-sub sockets.4.10.3 PotentiometerPotentiometers with resistances between 1 kOhm and 10 kOhmare connected in a three-wire configuration.Fig. 4-40 A107, measurement with potentiometers; left: terminalversion; right: D-sub sockets.4.10.4 Resistance, Pt100, Pt1000You can connect resistances and Pt100/1000 probes in two-wireor four-wire circuits. You specify the selected type of circuit dur-ing the module configuration (Type column).Fig. 4-41 A107, measurement of resistance and Pt100/1000 probes;left: terminal version; right: D-sub sockets.I2, 7 (+)5, 10 (GND)I9 (+)8 (GND)1, 65, 10 (GND)2, 718 (GND)92-wire circuit4-wire circuit1, 62, 71, 64, 92, 73, 8191792
