It carries 4 digital inputs and 4 relay outputs for standard control, plus 16 fail-safe digital inputs and 4 fail-safe digital outputs for safety functions like emergency stops and light curtains. The 125KB memory handles the application logic and safety program together, but the non-expandable form factor means you size it for the final I/O count upfront — no adding modules later. The 1214 BC is a fail-safe CPU, meaning the onboard safety I/O can run PROFIsafe over the backplane without a separate safety module. The 4 fail-safe outputs are relay type, so they switch loads up to the relay rating directly — no external interposing relays needed for the safety path. Because the CPU is non-expandable, the 16 fail-safe inputs and 4 fail-safe outputs are the entire safety budget. If your safety matrix needs more than 4 outputs, this CPU won't stretch — you'd step up to an expandable fail-safe CPU or add a remote safety I/O station. For a line-down spare or a new build, this CPU is sourced to order against your BOM.","metaTitle":"Siemens 6ES72141KF400XB0 SIMATIC S7-1200 CPU 1214 BC, 125KB","metaDescription":"Siemens 6ES72141KF400XB0 SIMATIC S7-1200 CPU 1214 BC safety PLC with 4 DI, 4 relay DO, 16 fail-safe DI, 4 fail-safe DO, 125KB memory.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["PLCs (Programmable Logic Controllers)"],"specifications":{"title":"6ES72141KF400XB0","Series":"SIMATIC","Package":"Box","Expandable":"Non-Expandable","Memory Size":"125KB","description":"CPU 1214 BC. 4DI/4DO/16F-DI/4F-D","lifecycle_stage":"current","Number of Inputs and Type":"4 - Digital","Number of Outputs and Type":"4 - Relay"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2,451.52","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy the 6ES72141KF400XB0 and get a price?","answer":"Send your BOM quantity for a current price and lead-time confirmation."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/6ES72141KF400XB0","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/6ES72141KF400XB0 when reusing this data.
