i have been running a project that require to read 4-20mA signal from AO module to AI Module. The module configuration is AO module on slot number 6, and AI module on slot number 5. they used white base unit (new supply group). But the 24VDC for supply come from same Power Supply. i have attached my wiring. Here is my problem. When i run the module, and i measure how much current on TB number 1 and 2. it shows 8mA (The AO program forced to 0). but when i measure both (TB 1,2 and 3,4) with 2 amperemeters. it shows correct value 4mA each. My first assumption is that H- terminal share the same M. so when i measure it is add of QI0+ and QI1+. Thanks for your help. AttachmentAttachment.pdf (354 Downloads) |
