I have a project where I need to connect four straight bar load cells. Can I use the combinator board to tie these together then use the amplifier board? The straight bar has four wires, but combinator board only has three inputs.
Combinator won’t work for 4 wire load cells, you need a summing box.
Amazon has one that’s not terribly expensive and that should work for you.

Nah, you only need the Combinator for the three wire ‘half bridge’ load cells. You can simply parallel your four wire cells.
