Product Description:

In order to avoid measurement errors, it is absolutely necessary, to lead the cores to the Pt100 sensors in the same cable. The cores must have the same cross section. Per channel, a twisted pair is used (for the two terminals of the Pt100 sensors) plus a single core (half of a twisted pair) for the connection to AGND1.Depending on the configured operating mode, the measured
value is assigned linearly see configuration table Fig. 4-18.The constant current of the one channel flows through the Pt100 resistance sensor, the constant current of the other channel through one of the wires. The basic unit 07 KT 94 calculates the measuring valuefrom the two voltage drops and stores it under the odd

Product's Character:

The 07 KT 94 unit linearizes the Pt100 characteristic.Temperatures that exceed the measuring range cause the overflow numerical value of +32767. If the measured value is below the range, the underflow numerical value of -32767 is set. In case of a detected open-circuit the numerical value of +32767 is set. If the sensor is short-circuited, the numerical value of -32767 is set.If the open-circuit or short-circuit monitoring is configured, the detected error is displayed by the red LED Ovl as long as it is present. In the PLC system an error message is stored (FK4, error number 9). In order to avoid error messages with unused analog inputs, it is useful, not to configure this channels
