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
