ABB Module DSDX180 3BSE003859R1 ABB DSDX180 ASEA CONTROL BOARD new version

Product Description:

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:

In the operating mode "Pt100 in 3-wire configuration" two adjacent analog inputs belong together (e.g. EW 6,00 and EW 6,01). For configuration, both inputs must be configured to the desired operating mode.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 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.
