The 14 DC-sinking inputs and 10 relay outputs cover the I/O count for a medium-sized standalone machine or a remote I/O node on a Profibus DP network — the relay outputs handle up to 2 A per channel for solenoid valves, contactor coils, or indicator lamps without an interposing relay. ## Memory, expansion, and fieldbus integration With 8 KB of code memory and 5 KB of data memory, the CPU 224 runs a moderate-size control program — ladder logic for a pick-and-place cell or a small conveyor system fits within this footprint. The Profibus DP extension allows the CPU 224 to act as a DP slave on a higher-level network, exchanging I/O data with a master PLC or SCADA system without adding a separate gateway module.","metaTitle":"Siemens 6ES7214-1BD21-0XB0 CPU 224, AC Supply","metaDescription":"Siemens S7-200 CPU 224 compact unit, AC power supply, 14 digital inputs, 10 relay outputs, 8 KB code/5 KB data memory, Profibus DP extendable.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["PLCs (Programmable Logic Controllers)"],"specifications":{"Part #":"6ES7214-1BD21-0XB0","Weight":"0.34 kgs","Category":"PLCs and Accessories","Sub Category":"Industrial Computer Board","Top Category":"PLCs & HMIs","lifecycle_stage":"current"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$292.10","priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/f197dc5500844272ef47c2d7b0a90673.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=240020&mlfb=6ES7214-1BD21-0XB0","alternativesUrl":"https://aoctrl.com/api/mcp/products/6ES7214-1BD21-0XB0/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy Siemens 6ES7214-1BD21-0XB0?","answer":"Submit a quote request for current availability and pricing."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/6ES7214-1BD21-0XB0","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/6ES7214-1BD21-0XB0 when reusing this data.
