Channels are isolated in groups of 4, so a fault or short on one group does not propagate to the other three groups on the same module. The 25 ms input delay filters contact bounce and AC ripple, which is standard for this signal class but not suited to fast pulse counting; a DC input module should be used where sub-millisecond response is required. Front connectors (screw-terminal or push-in) are not included and must be ordered separately.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cp\u003eReading 230 V AC field signals such as limit switches, pushbuttons, and relay contacts directly into an S7-1500 station without signal conversion, in cabinets where mains-voltage field wiring is standard practice.\u003c\/p\u003e","brand":"Siemens","offers":[{"title":"Default Title","offer_id":53960647475483,"sku":"6ES7521-1FH00-0AA0","price":313.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0903\/7722\/4475\/files\/siemens-6es7521-1fh00-0aa0-di-16x230vac-ba-module.png?v=1789714758","url":"https:\/\/stoklink.com\/products\/siemens-6es7521-1fh00-0aa0-di-16x230vac-ba","provider":"Stoklink","version":"1.0","type":"link"}
