The module’s inputs are a 24 V DC nominal type with an on-state current of 4.8–5.5 mA (10–31.2 V), off-state current up to 2.27 mA, and an off-state voltage maximum of 5 V, with input delay times specified as 380 µs max from Off to On plus a user-selectable filter of 0, 1, or 2 ms, and 420 µs max from On to Off plus a filter of 0, 1, 2, 9, or 18 ms; the backplane power draw and dissipation are 120 mA at 5.1 V and 2 mA at 24 V, with a total backplane power of about 0.66 W and maximum module power dissipation of 6.2 W at 60 °C (140 °F), equating to a thermal dissipation of 21.1 BTU\/hr at that temperature. With 32 discrete inputs, the IB32 is ideal for reading switches and 24 V sensors in industrial automation, manufacturing lines, and other ControlLogix-based control applications requiring a dense, reliable 24 VDC input interface.\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51657301524782,"sku":null,"price":145.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_b19f9fed-3680-41cf-85dd-60a160377714.jpg?v=1769467685","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1756-ib32-32-point-digital-input-module","provider":"PLG Automation ","version":"1.0","type":"link"}
