It accepts 79–132 V AC (nominal 120 V AC) at 47–63 Hz and is configured as a backplane I\/O module in the 1756 ControlLogix architecture, delivering field-side diagnostic feedback for connected devices such as switches and sensors. Each group contains four inputs with no isolation between individual inputs within that group, enabling compact, two‑group monitoring of AC signals. The module draws about 100 mA at 5.1 V and 3 mA at 24 V, with a maximum power dissipation around 4.5 W at 60 °C and total backplane power near 0.58 W, reflecting its role as a 8‑point diagnostic input device in industrial control panels. Catalog number 1756‑IA8D specifies its function as an AC diagnostic input module, and its design supports reliable status and fault feedback within ControlLogix systems, making it suitable for applications that require continuous monitoring of AC field devices and integrated diagnostics within a Rockwell Automation backbone. \u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51658939859246,"sku":null,"price":421.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_b2d70197-7f4d-4c2f-bb92-ca6d849f087b.jpg?v=1769525733","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1756-ia8d-analog-input-module","provider":"PLG Automation ","version":"1.0","type":"link"}
