{"product_id":"siemens-6fx1118-4aa01-industrial-safety-relay","title":"Siemens 6FX1118-4AA01 Industrial Safety Relay","description":"\u003cdiv\u003e\u003cp\u003eSiemens 6FX1118-4AA01 is an industrial SINUMERIK in-\/output module that provides a high-density digital I\/O interface for older Siemens CNC control systems. The module offers 48 input points and 24 output points, enabling a compact expansion of I\/O connections for sensors and actuators in machine tools and other automated equipment. Classified as part of the SINUMERIK 3 family, the 6FX1118-4AA01 is designed to be integrated with compatible SINUMERIK controllers to centralize digital I\/O functions in a single chassis module. As an obsolete product, Siemens discontinued this model on June 30, 2005, and it is no longer manufactured or stocked new by Siemens; compatible units may be found as refurbished or used through third-party suppliers. Typical scenarios include retrofitting or maintaining legacy SINUMERIK installations that require additional input and output channels without upgrading to newer I\/O platforms. When sourcing this part, verify compatibility with your SINUMERIK controller and any relevant service documentation, and consider replacement options from current Siemens I\/O modules if you are starting a new project. The 6FX1118-4AA01's design focuses on reliable digital signaling within the SINUMERIK ecosystem, providing a straightforward expansion path for existing CNC or automation setups that rely on a multi-channel I\/O architecture.\u003c\/p\u003e\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"New Surplus No Box","offer_id":46268604121322,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-018.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/siemens-6fx1118-4aa01-industrial-safety-relay","provider":"GTG Hardware","version":"1.0","type":"link"}
