Convert differential to SE output

I have an AD module with several single-ended analog (0-5VDC) inputs. The
problem is that I'm trying to use it to read the analog out (0-5VDC) of
three identical but separate devices. I'm afraid to just connect all of
their (-) outputs together to make then single-ended and see what happens.
How can I convert their differential outputs to single-ended?
thx

Why not just connect all their (-) outputs together and see what
happens?

At $50 per module I'd hate to lose one or two in the process.
