Mydaq maximum voltage

[No-brains-for-days]

I was wondering what the maximum voltage a mydaq can take before it "breaks". I found that it stated that the maximum voltage range was 60v, and just wanted to verify whether this was the max it can read, or if that is its biggest unit of accuracy?

I have never used one, but looking at the manual I would not go over 60 VDC on the DMM input.  You might be able to go a few volts over, but then you might let the magic smoke out as well.  If you need a higher voltage you might want to look into voltage dividers.

The myDAQ should not be used to read voltages outside the 60 VDC/20 Vrms, Measurement Category I.

In addition to what Bryan said, the input protection fuse for the DMM inputs are listed on page 9:

"Input protection Internal ceramic fuse, 1.25 A 250 V, fastacting, 5 × 20 mm, F 1.25A H 250V (Littelfuse
part number 02161.25)"

Also please keep in mind the Analog Input (AI) connections are subject to different input ranges and protection voltages.
