Hi, All,
Some control devices (like Japanese PLC) seperate 24VDC 0V (Signal Ground) from PE (Frame Ground), but some European products link these two grounds together inside the device. Can anyone tell me what is the pros and cons of these two different
grounding approaches? In practice, if we have these two kinds of devices in the same system, should we link the two grounds together everywhere or still seperate until linking together at only one point?
Thanks a lot!
