It reads field devices such as pushbuttons, limit switches, proximity sensors, and relay contacts and reports their states to the S7-300 CPU over the backplane bus. The inputs are optically isolated from the backplane bus.\u003c\/p\u003e\u003cp\u003eThe module mounts on the S7-300 rail and requires a 1x 20-pin front connector (sold separately).\u003c\/p\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSeries\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSIMATIC S7-300, SM 321\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eModule type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eDigital input module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eInputs\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e16 DI, isolated\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eInput voltage\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e120\/230 V AC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFront connector\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1x 20-pin (required, not included)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eStatus indication\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eGreen LED per channel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMounting\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eS7-300 mounting rail\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e","brand":"Siemens","offers":[{"title":"New","offer_id":47273553035500,"sku":"6ES7321-1FH00-0AA0-FS","price":601.95,"currency_code":"EUR","in_stock":true},{"title":"New Open Box","offer_id":45000656847084,"sku":"6ES7321-1FH00-0AA0-NSO","price":0.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0217\/1112\/6600\/files\/siemens-6es7321-1fh00-0aa0-new-591.jpg?v=1785800443","url":"https:\/\/www.industrialautomationco.com\/it-it\/products\/siemens-6es7321-1fh00-0aa0","provider":"Industrial Automation Co.","version":"1.0","type":"link"}
