Dear UMENCHO 1. What do You mean by ""health" grounding there"? 2. I removed grouding only by AI module by 4-20mA source, M- in every channel is ungrounded. (Even that manual says it is good to ground all M-) 3. I didn't measure now Volatage between M- & G. What value do You expect? Dear Marcjan 1. Manual says that to ground every M-. Also notused one. Otherwise there can be some influeance (or something like that) Dear Aret 1. Do you mean to not ground 0VDC of 24VDC supply? 2. The CPU doesn't have GND connector. I thought it is grounded by the Rail. 3. There is only one PS for CPU and AI module. 4. Can You give an example of good supply connection of AI and CPU to avoid problem in future. |
