Hi;

Is there galvanic isolation in 6ES7134-6GF00-0AA1 and 6ES7135-6HD00-0BA1 products?

Split from Galvanic Isolation.

Hello,
there is nothing in the manuals about galvanic isolation.
You can create a support request to ask Siemens directly.

It is not explicitly stated, but if you take a look at the internal schematics at chapter 4.3 of the manual (6ES7134-6GF00-0AA1):

you can see that all of the inputs are referenced to P2 (M) trough a resistor and pin 9-16 are all bridged together.

The only galvanic isolation is between the A/D converter and backplane BUS.

The situation is pretty much the same for 6ES7135-6HD00-0BA1

There is some additional isolation between the power supply L/M, but all the outputs are referenced to a common potential.

You will have to use external isolators, or use a single module for every IN/OUT with a white BU if you want to achieve real galvanic isolation between channels.
