Each channel carries a dedicated LED indicator for at-a-glance field signal verification and troubleshooting. The 1 mA off-state current prevents false triggering from line leakage. Faster 15 ms response on DC signals suits time-critical interlocks. At roughly 0.35 kg, the module adds minimal weight to the chassis. It mounts directly to any 1746 local or expansion chassis bus connector.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical FAQs\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eQ1: How many channels and what voltage does it accept?\u003c\/strong\u003e\u003cbr\u003e\n\u003cstrong\u003eA1:\u003c\/strong\u003e 16 sinking channels at 24VAC\/VDC nominal, operating over 10–30V.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ2: What is the signal delay for AC versus DC?\u003c\/strong\u003e\u003cbr\u003e\n\u003cstrong\u003eA2:\u003c\/strong\u003e 15 ms for DC signals and 25 ms for AC signals on both transitions.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ3: How much backplane current does it draw?\u003c\/strong\u003e\u003cbr\u003e\n\u003cstrong\u003eA3:\u003c\/strong\u003e 0.085 A at 5V DC, with 6 W total power consumption.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":67637033468036,"sku":"1746-IN16","price":180.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0958\/7454\/7844\/files\/1746-IN16-2.jpg?v=1791555765","url":"https:\/\/www.etowonauto.com\/vi\/products\/1746-in16-slc500-allen-bradley-digital-input-16-ch-24vac-vdc","provider":"Etowon Auto","version":"1.0","type":"link"}
