Vers. No. 4.062 Released: 5/12/20114 Connecting the modules → Q.bloxx A107: Connecting sensorsTipInformation about the types of circuit and the respective advan-tages and disadvantages can be found in Section 6.3, Connectingsensors with sensing leads, Page 115.4.13.5 ThermocoupleFor connecting thermocouples you need a special connectingplug which contains the comparative measuring point (cold pointcompensation) required for thermocouples. The plug can beobtained under the designation Q.bloxx Terminal CJC-A107 fromGantner Instruments Test & Measurement GmbH. You can con-nect the following types of thermocouple: B, E, J, K, L, N, R, S, Tand U.Alternatively, you can also use two thermocouples or a referencetemperature source.TipYou will find information on the comparative measuring point andon the measurement with a reference temperature source inSection 6.6, Measuring with thermocouples, Page 119.Fig. 4-53 A107, measurement with thermocouple using Q.bloxxTerminal CJC-A107.4.13.6 Full-bridge transducerWith (resistive) full bridges (strain-gauge full bridges) four con-nections are occupied. If the sensor has sense leads, you shouldconnect them to the relevant supply lines (1 and 5 or 6 and 10).The bridge excitation voltage is 2.5 V.3, 7 (–)2, 6 (+)Q.bloxx Terminal CJCCJC–CJC+
