#168 - What are the main differences between these two Digital Input Cards

What's the main differences between these two Digital Input Cards:

6ES7131-6BF01-0BA0 vs. 6ES7131-6BH01-0BA0.

#167 - Wiring some Digital Input sensors

Digital Input sensors are very common in the industry, and they can inform the system about different types of information. Here below some of the most common examples.

#166 - Siemens Analog Input 2-Wire vs. 4-Wire

Analog Input sensors can be in different configurations, such as 2-wire and 4-wire.

Depending on the chosen configuration, there are some points to watch out, in particular: how to wire the ground reference and how to wire the analog input signal or current loop.

#165 - Siemens PN/PN Coupler

The PN/PN Coupler is a great product from Siemens (ref. 6ES7158-3AD10-0XA).

It has two independent PROFINET cards that enable the data transfer between two different industrial networks, X1 and X2.
