Designed as an open-style I\/O module, it provides eight discrete input points that read AC on\/off states from field devices when connected to a 1746 chassis. Key electrical characteristics include a nominal input voltage of 100–120 VAC at 50\/60 Hz; per-channel input current of about 12 mA at 120 VAC; an off-state current of up to 2 mA and an off-state voltage of up to 30 VAC; signal delays of approximately 35 ms on and 45 ms off; and an inrush current spec of up to 0.8 A for up to 0.5 ms. Backplane current consumption is about 0.050 A at the 5 V rail for the IA8, aligning with other IA-series modules, and the unit is designed to mount in an SLC 500 rack alongside other I\/O modules to share a common backplane. Typical applications include expanding discrete input capability for sensors, switches, and other binary field devices in legacy SLC 500 automation setups that require 115 VAC input signaling.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New Surplus No Box","offer_id":51657308111150,"sku":null,"price":28.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_81520b19-b860-4cf3-9d11-06e970bcc682.jpg?v=1769467749","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1746-ia8-slc-500-digital-input-module","provider":"PLG Automation ","version":"1.0","type":"link"}
