Mine came off eBay from Longs Motor as a kit with 4 x DM542A stepper drives. Here's a listing

But look around first as I think there are multiple suppliers.

30 dollars...hhhmmmm
It is not so cheap...

I think i am going to connect them directly without bob. Is there any problem ? They are only switces with external pull ups. No relays or motors

There are straight through unprotected screw terminal breakouts fairly cheaply, that you can wire however you like.

Funny, I said there are others, but darned if I can find any now.

It wouldn't particularly worry me to do that.

You could make an opto-isolation board very easily if you wanted, too. Just use some strip-board.
