NI 9219 Chanel out of order

Hi,

we're using NI 9219 + NI cDAQ-9181 on several production equipments to measure voltage and current on the produced parts. We're currently facing several chanel breakdown on different equipments. We are using those chanels around 2 seconds each 2 minutes, 24 hours a day, 7 days per week.

Is there any known "lifetime" limitations for those equipments? Or someone did already face such issue and found any root cause?

Thanks for your support
