Terminals in Automation Studio

Hi there!, Can anyone help me with terminal block definitions.. I got feed-through triple deck 3 circuits of 2 connections. Where I can read about terminal block theory? Thanks in advance!

Welcome to the forum.

maybe this will help.
simply put, a terminal block is a device used to connect 2 different wires through the device by means of a screw terminal on each side of the device.

single level terminal blocks, are just that. 1 wire in, terminal block, 1 wire out

two level terminal blocks are typically 2 single terminal blocks, one on top of the other with no electrical connection. I use these type of terminals for 2 wire sensors such as prox switches, reed switches, photo cells....

three level terminal blocks are typically 3 levels of terminal blocks with no connection between levels. use these for dc 3 wire prox switches, phtos…

you use the multi level terminals to eliminate the need for a lot of terminal blocks and to keep all the sensor wiring together. for example, a 3 wire dc prox switch would require (3) single level terminal blocks or only (1) 3 level terminal block. the bottom level could be dc common, the next level could be dc+, and the top level is the sensor output going to the plc input.

when you have multiple 2 and 3 level terminal blocks, you can order a jumper bar to connect all the dc+ and dc common terminals together, rather than using a lot of wire.

there may be special types of terminal blocks out there that I am not aware of. these are the ones that I use for general I/o wiring. power wiring terminal blocks have 1 large wire in and multiple smaller wires going out.
I hope this helps,

Thanks a lot but it says decks , not levels and it is not the same...

Do you have a brand name, part number, picture?

Thank you for answer please see an attchment

and this

From the datasheet "The upper level is for signal wiring, whereas the two lower levels are used to distribute the positive and negative potential"

And from a supplier:

It refers to levels, so I think levels and decks can be considered the same meaning
