What are the limits of the PCI-6023E's overvoltage protection?

What are the limits of the PCI-6023E's overvoltage protection to its analog inputs using RSE? How much voltage can it handle before it is damaged? How many times can it handle a 100V input before it is damaged?

[JB]

According to the specifications (page 3), the max voltage is much less than 100V !

stoico,

JB is correct.  The maximum working voltage (from channel to ground) is +-11V. The overvoltage protection is as follows:

                                 Signal Powered                               On Powered Off

AI <0..15>                  ±42                                                     ±35

AI SENSE                   ±40                                                    ±25

I would also not recommend running this at 100V.
