Product Description:

The basic unit linearizes the Pt100 characteristic. Temperatures which exceed the measuring range cause an overflow error message. If the measured value is below the range, an underflow error message is generated. A detected open-circuit causes an overflow error message. If the sensor is short-circuited, an underflow error message is generated. 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 for Pt100.

Product's Character:

Output ranges ±10 V / 0...20 mA / 4...20 mA In case of voltage outputs the max. output current is
±3 mA. The output is short-circuit proof. In case of current outputs, the range of permissible output
load resistors is 0...500 W. If in case of an error the outputs are switched off, this means the following:
Configuration ±10 V 0 V Configuration 0...20 mA 0 mA Configuration 4...20 mA 0 mA. The basic unit calculates the measuring value from the two voltage drops and stores it under the odd address (e.g. EW 6,01).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.
