Hello everyone!

This is my first post here.

I would like to know whether there is a thread/post from someone who has added the complete list of equipment and instructions for connecting a Lee Pro 4-20 pot to a PID controller. I have seen the 2011 post but not all the links work anymore and references to photos or the pictures themselves are gone. To add to this I am in South Africa so I'm looking for the equipment which would work with a 240V grid. Many thanks!

The 120v PID setup is the same as the 240v setup with the exception of the plugs.

The majority of PID controllers operate on a wide range of voltage (typically 85vac to 265vac)
The PID generates the DC signal voltage (@8vdc) for the Soild state relay (SSR)

On the SSR you’re only switching 1 leg of the 240 just like the 120v setup.

Send me a PM with any questions you can’t figure out.
