ABB Module DSQC239 YB560103-CH ABB DSQC239 Remote I/O Board High reliability

Product Description:

For configuration, both inputs must be configured for the desired operating mode, see configuration table Fig. 4-18. The measured value is calculated by subtraction. The value of the channel with the lower address is subtracted from the value of the channel with the higher address.The converted measured value is available on the odd address (e.g. EW 6,01). Important: The common mode input voltage range equals the measuring range of the single channel. I.e. that the signals,related to AGND, at the two involved inputs must not exceed this measuring range.

Product's Character:

When resistance thermometers are used, a constant current must flow through the measuring resistor in order to create the necessary voltage drop for the evaluation. For this purpose, the basic unit 07 KT 94 provides a constant current sink, 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).
