This 21-slot backplane rack provides space to mount the central unit and compatible expansion modules, and it ships without a CPU, battery, or manual. The rack is configured for 230 V AC input and an internal 5 V rail to power the backplane, with a current rating of 18 A to support installed modules. Used in legacy S5 automation setups, it serves as the central chassis for CD 135U\/155U configurations, enabling organization and distribution of control signals across all slots. For a complete system, pair this rack with the appropriate CD 135U or CD 155U central unit and the necessary expansion or I\/O modules to realize a full SIMATIC S5 control scheme.\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46268494971114,"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-6es5188-3ua12-rack-controller-module","provider":"GTG Hardware","version":"1.0","type":"link"}
