Connecting Floating differential and Voltage divider to NI9205



Please find below my wiring configuration, I have a couple of questions about that - Kindly help with the same


  1. I want to connect two floating sources as differential measurement and as suggest  in the manual, I'm also connecting 1Meg to COM terminal - Please confirm if my understanding is correct
  2. In one of the floating sources the voltage range to be measured is around 50V, So I'm planning to put a simple voltage divider and then take it NI-9205 and configure this also as differential - will this work or if there is any downside to the same
  3. I have a couple of grounded single-ended measurements to make - Which is configured as NRSE and COM & AISENSE are shorted 




Thank you
