Notably, the Ether1616 inputs can also be configured either current-sinking or current-sourcing, so they can support PNP devices.

typically probes are not connected to the ether1616 if super accuracy is desired, since the ether1616 is not as fast as the Acorn inputs by a factor of 10.
see the ether1616 manual for guidance in this regard.

I remember you stating this before in another post Keith but worth mentioning again.

As I also mentioned before just a few posts ago in this topic the same goes for using relays and SSR (or any other device/circuit) to invert a PNP to NPN or visa-versa. There is latency in switching devices and if you want precision out of a probe buy the correct one for the input type you are using.

If you are making wood widgets on a router this may not be an issue.

Interfacing a 12V device to work with the Acorn is not complicated, needing only an opto-coupler, a few resistors, a diode, and a transistor; but, to be reliable, you would have to have a circuit board made. It doesn't make a lot of sense to design a new circuit board when you can buy a sensor that works with the Acorn for $25 or less. However, if you want a schematic to make your own board, send me a private email and I'll try to help.
