Hi,
The serial number is 153DF7C
I logged with DAQami at 4Hz and it crashed after 8723 readings
Perhaps the test Hardware- wiring enclose is cause a spike from the switching .
Should I add a capacitor across the supply pins 29-30
Or are there any other recommendations
Thought I sent the above, but I have now run the unit logging at 4Hz and with no switching of the relays it ran for over 4 hours 588800 only stooping on the time out set
So i need to de-bounce the contacts
Your signal connection guide suggest a low pass filter but not sure how to apply this to my circuit

I have tested the board with no connections and it passes.,
The only difference with by logging set up is I selected Digital in only
With 4Hz it logged 1861 samples before error
with 2 Hz 7439 samples
with 1Hz 1051 samples

I tried the test but port A fails the test with the hardware connected as this ground all 8 digital inputs of the port .
I have not disconnected the inputs to check if it still fails.
When logging it works fine for a while then crashes
Am I exceeding the sampling speed of the 1024LS?

usb-1024LS fails with error " Error: 2 Dev0 Error: Digital device is not responding." logging on TracerDAQpro - 8 channnels digital in montoring relay switches wired as figure 3.3 of User guide logging at 4 Hz, also fails on 2 and 1Hz

Hi,nt
I noticed this circuit in your guide but could not see how-to implement this in my circuit.
i am going to try to debounce the contacts using a Schmitt trigger chip
