It supports sinking or sourcing 24 V DC input operation, enabling flexible wiring to pushbuttons, limit switches, proximity sensors, and auxiliary contacts. Widely used in industrial automation to receive signals from field devices, the 1756-IB16I supports high-density input monitoring in manufacturing plants, oil and gas facilities, water treatment systems, packaging operations, and automated production lines where accurate and isolated input detection is essential. Typical applications include I\/O expansion, module replacement, system upgrades, and integration of field input devices into PLC-based control systems, with backplane current draw described as application dependent. Common replacements include Allen-Bradley 1756-IB16 and 1756-IB16IF, with Siemens 6ES7521-1BL00-0AB0 listed as a cross-reference in some control architectures.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Surplus Original Box","offer_id":50558369726766,"sku":"Surplus Original Box","price":273.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/1756-IB16I.jpg?v=1752201446","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1756-ib16i-16-point-digital-input-module","provider":"PLG Automation ","version":"1.0","type":"link"}
