Issue with outputs on USB-DIO24/37

[Bret.PID.Analyzers]

Hello, we're using a USB-DIO24/37 as a controller in a product for an automated process. I've run into an issue where for some reason the pin being used to activate a gain stage on an amplifier board isn't switching. The outputs are all set to be pulled down when not activated, and I usually see the 5V when I turn a point on and off. When I measure the output for the pin controlling the amp board gain though, it only goes to about 70mV. We tried moving the board to a different input that uses a different pin to activate this feature, but it garnered the same result. Furthermore, when I measure this output while not connected to the board, it's still reading about 70mV. This is the first time I've seen this happen in years of using this board like this, and I'm concerned that the output may have been damaged by an issue with the amplifier board. Is it safe to assume this, or is there something I might need to change to revert this? Thank you!

Hello @Bret.PID.Analyzers.

I moved your question to the Measurement Computing (MCC) section of the Forum.

Is the MCC USB-DIO24/37 device new or has it been in use and working correctly?

Do you have another USB-DIO24/37 device to swap in and test with your equipment?

Regards,

Hello @Fausto! Apologies, I thought I had posted this in the correct place. The board was purchased new for this unit, but has otherwise been working correctly. We unfortunately do not have another USB-DIO24/37 to swap it with. The other thing supporting the idea that the output is damaged is that there are several other pins being used by that port (Port A), and they all function as needed. The unit also uses a USB-1608FS-OEM, so I asked the programmer to move that command to an output on there to be able to test further. I also need to make a modification to the amplifier board that output is going to today, so I should be able to try and test that input to see if there's something wrong on the amplifier board's end as well. I've been able to get it to switch correctly on the test rig I have, but that also can provide a great deal more current than the pins on the DIO24/37 can. I'll be able to report back with more info that might help later. Thank you!
