The 6ES7223-1HF22-0XA0 is a Siemens SIMATIC S7-200 EM 223 digital I/O expansion module designed specifically for S7-22X CPU families, including CPU 221, CPU 222, CPU 224, and CPU 226. This module extends the digital I/O capacity of the base system, offering a balanced mix of 16 inputs and 16 outputs in a compact form factor. The inputs accept 24V DC signals, while the outputs are configured as relay contacts, providing galvanic isolation and compatibility with both AC and DC loads up to 2A per channel. The module communicates with the CPU via the integrated S7-200 backplane bus, requiring no additional power supply or complex configuration. Ideal for applications requiring additional I/O points in existing S7-200 installations, such as packaging, material handling, and simple machine control, the EM 223 ensures seamless integration and reliable operation in industrial environments. Below are the detailed technical specifications:
