I do this using a "T" splitter and two cables. No problems with other pressure sensors that use pins 1(+) and 2(-). But in P200 case the pins are1(+) and 3(-). I have checked more connector manufacturers and most of them expect analog signal at pins 1 and 2. If signal comes on pins 1 and 3, I can't use splitters. Siemens provides cables with M12 connectors ? How to change signal pin from 3 to 2 ? Thank you.

Please have a look the schematics attached and find the right cable for your connection. Regards, Chook Attachment 7F905d01.pdf (149 Downloads)

Suppose both pressure transmitters had signals on 1 & 2. Will a Tee splitter actually do what you need? cable 1 Splitter common 1 1 2 2 cable 2 13 2 4 I don't know, I'm asking. It's obvious that a number of vendors provide cordsets with an M12 connector on one end and flying leads on the other end and that you can run the flying leads to terminal blocks to produce and configuration of wiring needed, but it's terminal block and maybe a junction box. I use breakout connectors for DB9 and RJ11 connectors that allow for custom wiring but when I have used commercial M12 cordsets I've noticed that gender changers are not available. I am unaware of custom configurable M12 connectors, probably because they have an IP rating that is incompatible with field assembled connectors.
