Designed to plug into a 1747 backplane within an SLC 500 chassis, it converts 24 V DC field signals into digital inputs that the controller can read for logic decisions. It uses current sinking (NPN) inputs, so an active device completes the circuit to a common ground, and it provides 16 discrete input channels that are commonly wired to sensors, limit switches, and other 24 V devices. The module is specified for fast response, with a module-wide scan time around 0.325 ms in typical configurations, enabling timely detection of state changes on production lines. As part of the 1747 I\/O family, the IB16 supports modular expansion of a legacy automation install, allowing integration with other DC input modules and PLC logic to implement machine control, safety interlocks, and process monitoring. In practical terms, it’s a drop-in digital input solution for projects that require 24 V DC signals and reliable, field-wiring-friendly I\/O in an industrial environment.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51658974626094,"sku":null,"price":123.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_bd30e8c1-8024-4d2c-9f11-a310e1588afe.jpg?v=1769526220","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1747-ib16-16-point-input-module","provider":"PLG Automation ","version":"1.0","type":"link"}
