Original supply of Siemens module 6ES7121HE310XB0 from Beijing

The S7-1200 module adopts a compact and modular design, with excellent functionality and investment safety, making it very suitable for various applications. It has a high degree of automated task execution capability and is easy to design and implement. In addition, this module also supports the application functions of small motion control systems and process control systems.

The 7-1200 series PLC currently has five main models: CPU1211C, CPU1212C, CPU1214C, CPU1215C, and CPU1217C. These models have differences in user memory, body integrated I/O, expansion capability, high-speed counting function and high-speed pulse output capability, PROFINET interface, and computing speed, etc., which can be selected according to actual application needs

Communication modules * *: These modules are used to enable communication between S7-1200 and other devices or systems. Up to three communication modules can be connected to the left side of all S7-1200 CPU controllers, facilitating end-to-end serial communication.
