Reply to "Putting in saftey relays"

The circuit of for this type of relay is simple. Looking at the base with the the two vertical terminals at the bottom: the vertical terminals are the coil. The horizontal terminals are the contacts. You can see how these directly exit the base of the relay. The top terminals are Normally closed, the middle terminals are the normally open. then the movable contacts. One pole is on each side.

This is an Omron part. I have attached a datasheet. The part number should be something like LY2N-xx where xx is the voltage.

I can find the LY2N-J part numbers on the web but haven't determined this significance of the suffix.

(Forgive all earlier versions of this post - not having a good day.)
