Issue Details

I don't know how to use the 100 ohm protection resistor in PXIe-2532B. I am not sure what role the 100 ohm protection resistor in the PXIe-2532B plays.

Solution

The resistor is used to isolate the unwanted effects of the load capacitance and limit damage to the relay contacts, such as inrush current. You could refer to Reed Relay Protection.

If you need to apply the protection resistor, several terminal blocks can be chosen with assembled 100 ohm for PXIe-2532B. When there's no need for the 100 ohm resistor, just use the shunts to pass them.
