Brother TC-211

One option is a 7I77D which is identical to 7I77 except has sinking outputs

I used transistors on the outputs. I don't remember which ones. I just shrink wrapped them right into the cable.

7i77d sounds better

If only 7i77d was available in Europe , I'll try to modify the relay board today. If not will go with adding the transistors to translate. Thanks

To add, I am amazed at the wiring masterpiece inside this Japan made machine, you literally can't move any wire. Wires are all wrapped, joined and cut to exact length. Finding which wire leads where is not possible with push pull method .
