The 6ES7212-1BA10-0XB0 is a field-proven SIEMENS SIMATIC S7-200 CPU 212 controller, designed for reliable discrete control in compact machinery and process lines. This unit features 8 digital inputs (24 V DC) and a robust CPU architecture that supports basic logic, timing, and counting functions. It communicates via the industry-standard PPI protocol, allowing direct connection to Siemens HMI panels and other S7-200 CPUs. With its 24 V DC power supply requirement, it fits perfectly into modern low-voltage automation environments. The CPU 212 is a legacy but highly dependable choice for retrofits and small-scale systems where simplicity and durability are paramount. Below are the detailed technical specifications:
