NI USB-9481 Switching Delay

One of the channels on my USB-9481 relay has begun operating with a delay between when the switch command is sent from LabView (or Measurement & Automation Explorer) and when the actual switching occurs. The other 3 channels appear to be operating normally. What might cause such a delay and how can the problem be resolved?

Hello JamesF,

 

Can you quantify the delay? I suspect its a faulty electromechanical switch, I recommend contacting National Instruments to service your device.  

 

Regards,

The delay is between 500 ms and 1 s. I'll contact NI for service.

 

Thank you!
