{"product_id":"siemens-6es7-138-4da01-0ab0-terminal","title":"Siemens 6ES7 138-4DA01-0AB0 Terminal","description":"\u003cdiv\u003e\u003cp\u003eSiemens 6ES7 138-4DA01-0AB0 Terminal is a SIMATIC ET 200S distributed I\/O terminal module designed to extend the I\/O capacity of a Siemens PLC. As part of the ET 200S family, this module plugs into the modular I\/O system to provide additional connection points for field devices, enabling scalable automation architecture across manufacturing lines and packaging cells. The 6ES7 138-4DA01-0AB0 designation identifies a specific terminal module variant within the 6ES7 138 series, allowing easy replacement and inventory management within standard Siemens hardware. Typical uses include expanding input\/output points for sensors and actuators in distributed automation networks, where centralized controllers coordinate multiple remote I\/O locations. The module supports standard Siemens engineering workflows and is compatible with the broader SIMATIC ecosystem, enabling integration with PLCs and project configurations created in STEP 7 or TIA Portal, depending on the system setup. In practice, users select this terminal when a Siemens ET 200S deployment requires additional I\/O channels without sacrificing compact cabinet space or centralized wiring, benefiting applications in automotive, packaging, and process industries that rely on robust, modular I\/O expansion. Exact electrical characteristics, signal type, and physical mounting specifications are specified by Siemens in the official product documentation for the 6ES7 138-4DA01-0AB0 order number, so validation against the system requirements is recommended before procurement.\u003c\/p\u003e\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46268525478122,"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-6es7-138-4da01-0ab0-terminal","provider":"GTG Hardware","version":"1.0","type":"link"}
