Q.seriesGantner Instruments Test & Measurement GmbH 534 Connecting the modules → Q.bloxx A103: Connecting sensors and I/OIMPORTANTVoltages which exceed the admissible limits produce incorrectmeasurement data, because the inputs are protected againstovervoltages and limit the input voltage.Fig. 4-35 A103, measurement of voltage.4.10.2 CurrentFor current measurement you need the connecting plug Q.bloxxTerminal SR containing the shunt resistances. This facilitates themeasurement of currents of up to 25 mA.Fig. 4-36 A103, measurement of current via Q.bloxx Terminal SR.4.10.3 Digital input and outputOn each connecting plug two contacts are available for an inputand an output.Fig. 4-37 A103, Digital Input and Output.The digital input is active (high level) when the applied signalvoltage lies above the threshold of 10 V.U3, 5, 7, 9 (+)4, 6, 8, 10 (–)I3, 5, 7, 9 (+)4, 6, 8, 10 (–)Input OutputDin Dout1+V0V2
