Hello,
I am working on a Windows 10 computer and Labveiw 2018 with a PCI 6503 connected to a CB-50 LP (NI part # 777101-01) terminal block. Hall sensors are wired into the block and powered by pin 49 (+5V) from the PCI 6503. For the past month, I have had 18 sensors wired and powered by the PCI device through the terminal block. However, today I noticed the voltage dropped to zero, and the sensors could not function. I disconnected all the sensors but one, and the voltage returned. As I rewired, the voltage decreased with each device I connected. I can only wire 6 of my 18 sensors before the voltage is too low. I have confirmed the voltage directly off the PCI is 5+V.
Any ideas on what the issue could be?
Thanks
