Siemens 6ES7212-1AE40-0XB0 SIMATIC S7-1200 CPU 1212C
The Siemens 6ES7212-1AE40-0XB0 is a SIMATIC S7-1200 CPU 1212C, a compact programmable logic controller with more onboard inputs and outputs than the entry-level 1211C model. It comes with a built-in power supply, digital and analog I/O, and a PROFINET port, so it can run as a standalone controller without needing extra modules. This makes it a good fit for small to mid-size machines that need a bit more I/O capacity than the base model can offer.

Description
The Siemens SIMATIC S7-1200 CPU 1212C sits above the entry-level 1211C in the S7-1200 family, offering more onboard I/O for machines with slightly higher input and output needs. It runs on a 24V DC power supply and includes 8 digital inputs, 6 digital outputs, and 2 analog inputs built directly into the unit, so there’s no need to add separate power or I/O modules for straightforward applications. This CPU is programmed using TIA Portal (STEP 7 V13 SP1 or higher) and supports LAD, FBD, and SCL programming languages, giving engineers the flexibility to write control logic the way they prefer.
The CPU 1212C includes a PROFINET port for network communication, supports open Ethernet protocols like TCP/IP and Modbus, and has a built-in web server for remote diagnostics. It also comes with useful onboard functions such as high-speed counting, pulse train outputs for basic motion control, and a PID controller for closed-loop process control. It can be expanded with 1 signal board, 2 signal modules, and up to 3 communication modules, giving you flexibility to grow the system without switching to a larger CPU.
