Siemens 6ES7214-1BG40-0XB0 SIMATIC S7-1200 CPU 1214C
The Siemens 6ES7214-1BG40-0XB0 is a SIMATIC S7-1200 CPU 1214C with a DC/DC/Relay configuration, combining the higher I/O count of the 1214C with relay-based digital outputs. It comes with a built-in power supply, onboard digital and analog I/O, and a PROFINET port, so it runs as a standalone controller without needing extra modules. The relay outputs make it well-suited for driving contactors, solenoids, and motor starters directly, without adding external interposing relays.

Description
The Siemens SIMATIC S7-1200 CPU 1214C DC/DC/Relay runs on a 24V DC power supply for the CPU itself, but uses relay outputs instead of transistor outputs, giving it the flexibility to switch both AC and DC loads directly. It comes with 14 digital inputs, 10 relay outputs, and 2 analog inputs built directly into the unit, so larger machines can be wired and running without needing separate I/O modules. This CPU is programmed using TIA Portal (STEP 7 V13 SP1 or higher) and supports LAD, FBD, and SCL programming languages.
The CPU 1214C DC/DC/Relay includes a PROFINET port for network communication, supports open Ethernet protocols such as 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, frequency measurement, and a PID controller for closed-loop process control. It can be expanded with 1 signal board, 8 signal modules, and up to 3 communication modules, giving plenty of room to grow the system later.
