It provides 32 independent 24 V DC outputs, each rated for 0.5 A, with the channels arranged in eight-output groups and configured as floating outputs (no common return inside the module) to give wiring flexibility for mixed load configurations. Designed for integration with an S5-115U\/F rack, this module enables direct control of 24 V DC actuators such as solenoids, contactors, and relays, supporting automation tasks in manufacturing lines, packaging, and machine control where discrete digital outputs are required. As part of the legacy SIMATIC S5 ecosystem, the 6ES5451-7LA11 remains a documented option for expanding output capacity in older installations that rely on 24 V DC logic and an S5 backplane, requiring appropriate power and backplane connections and adherence to the 0.5 A per-channel specification.\u003c\/p\u003e\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"New Surplus No Box","offer_id":46268509683946,"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-6es5451-7la11-programmable-logic-controller-module","provider":"GTG Hardware","version":"1.0","type":"link"}
