It provides 16 digital inputs at 24V DC and 16 digital outputs at 24V DC in a single unit, which simplifies the I/O map for a machine section that needs balanced point counts on the same potential.","metaTitle":"Siemens 6ES7223-1BL20-0XA0 EM 223, 16 DI / 16 DO, 24V DC","metaDescription":"SIMATIC S7-200 EM 223 digital I/O module, 16 inputs 24V DC, 16 outputs 24V DC.

It connects via the side bus connector and draws its 24V DC field power from the CPU or an external supply."},{"question":"Is the 6ES7223-1BL20-0XA0 compatible with S7-200 CPU 226?","answer":"Yes, the module is compatible with the CPU 226, as it belongs to the S7-22X family. The CPU 226 supports up to 7 expansion modules, and this EM 223 counts as one of them."},{"question":"What is the difference between 6ES7223-1BL20-0XA0 and 6ES7223-1BL20-0XB0?","answer":"The evidence does not detail the difference between these two order codes. Both are EM 223 modules with 16 DI / 16 DO at 24V DC; the -0XB0 suffix typically indicates a later hardware revision or a minor variant. Confirm the exact order code on your nameplate before ordering."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/6ES7223-1BL20-0XA0","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/6ES7223-1BL20-0XA0 when reusing this data.
