No, it's designed for NC only. NO switches can just be wired in parallel. I wanted to keep NC proximity switches for all the good reasons, but in order for...

Ha. I just realized my new boards won't work the way I intended. I need to make some changes and re-order. Such is life.

Is there any way you could provide a snippet of the schematic for the new board around the limit switch inputs? I believe you said you were adding isolated 12V...

Great, thanks! Is the order of the inputs in the schematic the same as on the board edge?

I'm in the process of redesigning my aggregator board. It looks like you set the current of the opto's to around 6.8mA. Do you think I could get away with...

I'm a little confused now. Your older board (non-pro) used 330 resistors, but the schematic you posted above uses 1.5K, which would yield 7.2mA. Or did you intend a smaller...

I use 805 myself, but that's just because I'm getting old and manually placing components smaller than that doesn't work for me. Oh, and I do have a reflow oven....

Power dissipation is the thing I almost always forget about. Circuit design is not something I do all the time so I get rusty. So, I just ordered some 1210...

So I must have been having a senior moment. I just realized there's no reason to have the LEDs in series with the optos. Since the sensors and optos are...

More questions about the upcoming pro board... 1. I believe you said you're using pluggable terminals. Are they vertical or horizontal entry? What pitch (3.5, 3.81, ...)? Do you know...
