ET 200S wiring example

Hello;

I am using ET200S distributed I/O system in my first project of BMS (Building Management System); i have to wire the circuit breaker of the electrical cells to my digital input module (6ES7131-4BF00-0AA0), but i haven't found a wiring example on the manuals of the modules.

I appreciate if someone can help me and show me an example of wiring because it's the first time of me.

In the eight terminals DIn, i wire the (+) or the (-) ? For the AUX terminals, what must be wired to?

The DI module must be powered or no? it gets his power from the power module ?

Thanks in advance.

By using the MLFB number on google search, you would of found a lot of answers. Here's just one of those.

Hello Hati; 

I have seen on google before asking here, but this not help me, i need more details, an example of wiring if it is possible.

I have two wires from my sensor or switch, so the negatif one is connected to the 1-8 terminals, and the positive one to the Aux terminals?! is it right?

Thanks in advance.

 If you have a 2-wire sensor, you basically don't have a minus. You have a common for the sensor and an output from the sensor. The common can be + or -, depending on the sensor.

You really need to read the PDF link i gave in the previous post, and read it good. Terminals 1-8 are inputs, not minus terminals.

Hi,

Modules are powered on with power supply modules, no need to giving the power supply on Aux terminals. please see the attachment.
