This new version is not done to correct customer issues.It is due to the use of a new analog digital converter component as the old one is no more manufactured.Schneider Automation has realized a new design to keep all the features of the new module identical to the old ones.But the new converter introduce a new way to supply the load cells.Before the power supply was 10V DC until SV2.3 .Now the power supply is pulsed , there are pulses of +5V and pulses of -5V while the converter do the measures. First thing for customer is that now he cannot check the load cell voltage with his multimeter. WARNING :All capacitors which could be in parallel of the load cells power supply have to be removed. 1_ It will affect the measures as they introduce a delay on the front of the pulses. 2_ The polarized capacitors will heat as now the load cell power supply is alternative.
