We have a USB-6210, which includes this information in the product manual:
Overvoltage protection for all analog input and sense channels
Device on ±30 V for up to two AI pins
(Emphasis mine)
We are testing a device which can technically output up to +/-20V on six channels, although we are not planning to operate it outside the +/-10V maximum sensing range of the USB-6210.
My question is, if our equipment were to output 20V on all six channels simultaneously, e.g. due to an EMC event making it malfunction, would that damage the USB-6210, or is it fine as long as all channels stay below 30V and we stay below the current limits?
I fully understand that the USB 6210 cannot measure beyond 10V, and that the readings will saturate to the sensing range configured by my software. I'm not worried about that, since my equipment will not be outputting beyond +/-10V as long it doesn't malfunction. I just want to make sure that I don't damage my USB-6210 if my device does experience a problem during testing and outputs 20V on all six channels at once, since that is the "worst case scenario" that the equipment is capable of generating.
