Siemens 6ES7214-1HG40-0XB0 SIMATIC S7-1200 CPU 1214C
The Siemens 6ES7214-1HG40-0XB0 is a SIMATIC S7-1200 CPU 1214C with a DC/DC/Relay configuration, combining the higher I/O count of the 1214C with relay outputs for direct load switching. 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 support a wide voltage range, making it flexible for switching devices at different voltage levels within the same panel.

Description
The Siemens SIMATIC S7-1200 CPU 1214C DC/DC/Relay runs on a 24V DC power supply for the CPU, but uses relay outputs that can switch loads from 5V DC up to 250V DC, giving it more flexibility than fixed-voltage transistor outputs. 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 extra 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 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.
