This 16-channel DO module is designed to plug into a compatible S7-300 rack and communicate with the central PLC over the SM322 bus interface, enabling reliable, discrete switching of external loads in automation applications. Each output channel delivers a 24-volt DC control signal to drive devices such as relays, indicators, or other 24 V DC actuators used in industrial control panels and machinery. The SM322 family is known for compact, modular expansion of output capability, allowing users to scale I\/O as process requirements evolve without replacing the core controller. The 6ES7-322-1HH01-0AA0 variant identifies a 16-channel digital output option in the SM322 lineup and is compatible with SIMATIC S7-300 CPUs and the associated rack architecture, supporting typical discrete control tasks across manufacturing lines, packaging machines, and automated tooling setups. The module is intended for use within Siemens' automation ecosystem, offering consistent electrical characteristics across the S7-300 family and straightforward integration with programming and diagnostic tools found in Siemens engineering environments.\u003c\/p\u003e\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46268586492138,"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-6es7-322-1hh01-0aa0-plc-input-output-module","provider":"GTG Hardware","version":"1.0","type":"link"}
