Connecting 36VDC to a Digital I/O device. Signal conditioning ideas

I'm making a test jig and I have about 32 output signals to check, they are all either 0-12VDC outputs or 0-36VDC outputs, I don't need to necessarily read their values (analog read), I just need to see that they turn on and off (digital). 

I thought this would be a perfect fit for a simple digital I/O device like this.

But it has a max input voltage of 5VDC.  Some of my signals are 36VDC.

I found these

and

But looks like I'm stuck for the 36VDC level because they only work up to 28VDC.

There has got to be a cheap way to bring all these outputs down from 0-36VDC to 0-5VDC.  I'd prefer not to make a custom board, but if I have to I will.  I would also entertain a large Analog input device that could read all these inputs and their voltages, but I have a feeling that would be VERY expensive to find a 32 point analog input card (>>$2K)

Any ideas?
