Fast 7.5 µs conversion captures rapidly changing variables. The 7 kHz bandwidth handles dynamic signals beyond standard analog modules. At roughly 0.2 kg, the module adds minimal weight to the chassis. Screw-terminal connections accept up to 14 AWG shielded cable for noise immunity.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical FAQs\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eQ1: How many channels does the 1746-FIO4I provide?\u003c\/strong\u003e\u003cbr\u003e\n\u003cstrong\u003eA1:\u003c\/strong\u003e 2 differential analog inputs (0–10VDC \/ 0–20mA) and 2 current outputs (0–20mA).\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ2: What is the resolution and conversion speed?\u003c\/strong\u003e\u003cbr\u003e\n\u003cstrong\u003eA2:\u003c\/strong\u003e 12-bit input and 14-bit output resolution, converting in 7.5 µs every 512 µs.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ3: What cable is recommended for wiring?\u003c\/strong\u003e\u003cbr\u003e\n\u003cstrong\u003eA3:\u003c\/strong\u003e Shielded Belden #8761 with wire size up to 2.5 mm² (14 AWG).\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":67637017804932,"sku":"1746-FIO4I","price":157.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0958\/7454\/7844\/files\/1746-FIO4I.jpg?v=1791552197","url":"https:\/\/www.etowonauto.com\/tk\/products\/allen-bradley-1746-fio4i-slc-500-fast-analog-i-o-module","provider":"Etowon Auto","version":"1.0","type":"link"}
