What's is basic difference between 8 DI AND 16 DI module? In 8 DI we have positive supply that we can use for external use . In 16 DI module we don't have any positive supply for external use all input connection are there. Any other points
I think you get the 24vdc from the power supply thats feeding that et200 module, I guess having the 16 di is just more inputs ?, im also having this question
