ABB Module DSQC334 3HAB5845-1 ABB DSQC334 Power Supply Module Performance great

Product Description:

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 Ω. 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 relationship between the numerical values and the
analog values given in figure 4-19 (analog inputs) is also valid for the analog outputs.The lithium battery 07 LE 90 can be inserted into the battery compartment in order to  backup data of user program in RAM backup data of additionally in RAM contained information, e.g. flag statuses backup of time and date.

Product's Character:

The battery lifetime is typ. 5 years at 25°C. The battery lifetime is the time during which the device remains operable in order to backup data while the supply voltage of the basic unit is switched off. As long as there is a supply voltage available, there is no more load on the battery other than its own leakage current. which is multiplexed to the 8 analog channels. The following figure shows the connection of Pt100 resistance thermometers in 2-wire configuration. it has to be measured bipolar in order to compensate measuring errors. Additionally, in case of singlepole configuration, AGND1 would be connected directly to the remote earth potential. This would cause inadmissable (and possibly dangerous) earthing loops. In all configurations using differential inputs two adjacent analog inputs belong together (e.g. EW 6,00 and EW 6,01).
