Hi Yunsong,
The file came through the same way, but no worries, I enlarged it and figured out what was connected.
First, please clarify which pin the "RTD return" connection is on your "PT100" terminal block. There are two "T2" net names even though there are three terminals. Is the "RTD Return" the top, middle, or bottom connection? I'm currently assuming it's the bottom connection.
Second, I'm having trouble understanding the function of the L10 inductor that seems to connect the isolated common output of the DCV device to the input common connection. This would seem to defeat the purpose of the isolation. Are you sure that the secondary side of the DCV device is truly floating in relation to your system or Earth GND?
