I dont know, I didnt design the DAQ board. And when I asked the error code to the manufacturer it didnt help. That's why I only know the reason is the interference the rest is unknown yet. All is that the DAQ stops functioning.
"Stop functioning" is more likely a problem of the digital controller or may be simple USB connection loss caused by ground common mode interferences than anything related to input signal spikes. You can try by disconnecting the hot signal line and keeping the ground.

Thanks I guess what you mean is to check if the problem is due to CM noise and bouncing ground .
If that is the case, would an opto coupler between the Arduino's signal output and the DAQ digital input help?
