Each of its 16 inputs is individually isolated from the backplane and from other channels to maximize noise immunity, with an operating voltage range of 79–132 V AC at 47–63 Hz (nominal 120 V AC). Electrical characteristics include an input impedance of 8.8 kΩ at 132 V AC, off-state voltage up to 20 V and off-state current up to 2.5 mA, and on-state current from a minimum of 5 mA at 79 V AC to a maximum of 15 mA at 132 V AC. The module’s internal electronics draw about 125 mA at 5.1 V and ~3 mA at 24 V, with total backplane power around 0.71 W and a maximum dissipation of 4.9 W at 60 °C (140 °F). Delay and filtering are configurable: screw-to-backplane delay is 10 ms max (off to on) or 8 ms max (on to off), with user-selectable input filter times of 1 ms or 2 ms (off to on) and 9 ms or 18 ms (on to off). The cyclic update time ranges roughly from 200 µs to 750 ms, accommodating fast sampling or slower observability as needed. Designed for isolating AC level presence in industrial automation, the 1756-IA16I is commonly used to monitor 120 V AC sensors and line-powered devices within ControlLogix systems, delivering reliable channel-to-channel isolation and straightforward integration into existing 1756 backplanes. \u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51658941268270,"sku":null,"price":317.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_b2298ddb-faa2-44d9-98a7-b18370941fa9.jpg?v=1769525742","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1756-ia16i-analog-input-isolated-module","provider":"PLG Automation ","version":"1.0","type":"link"}
