This device reads dual-state signals from external electrical paths, managing a density of up to 8 channels over an operating input range of 10-27V DC. This input module is fully compatible with standard 2-wire and 3-wire automation components including DC proximity switches, photoelectric sensors, pushbuttons, limit switches, float switches, and selector switches. To ensure signal clarity under harsh environments, it incorporates built-in filtering mechanisms that limit electrical fluctuations before they reach the controller logic.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eIntegrated input filtering logic circuit to mitigate voltage transients caused by contact bounce and radiated electrical noise.\u003c\/li\u003e\n\u003cli\u003eNative backend connectivity matching standard 1771 I\/O chassis backplane lines for power distribution.\u003c\/li\u003e\n\u003cli\u003eFull structural operational compatibility across both two-wire and three-wire control path field devices.\u003c\/li\u003e\n\u003cli\u003eShipped in specialized protective static-shielded packaging to minimize standard handling damage from electrostatic discharge.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eInterfacing discrete industrial machinery status loops with main automation units.\u003c\/li\u003e\n\u003cli\u003eIndustrial sensor network synchronization using proximity or photoelectric arrays.\u003c\/li\u003e\n\u003cli\u003eMachine tool tracking and safety interlocking layouts using pushbuttons and limit switches.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ch4\u003ePerformance and Electrical Specifications\u003c\/h4\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer\u003c\/td\u003e\n\u003ctd\u003eAllen-Bradley\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003e1771-IB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUPC\u003c\/td\u003e\n\u003ctd\u003e662468205474\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCountry of Origin\u003c\/td\u003e\n\u003ctd\u003eMexico\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModule Type\u003c\/td\u003e\n\u003ctd\u003eDC (12-24V) Input Module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Channels\u003c\/td\u003e\n\u003ctd\u003e8\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Signal Range\u003c\/td\u003e\n\u003ctd\u003e10-27V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBackplane Current Requirement\u003c\/td\u003e\n\u003ctd\u003e74mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Off-State Leakage Current\u003c\/td\u003e\n\u003ctd\u003e3mA (for 3-wire devices)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNominal Input Filter Delay (Turn-On)\u003c\/td\u003e\n\u003ctd\u003e12 + 7 ms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNominal Input Filter Delay (Turn-Off)\u003c\/td\u003e\n\u003ctd\u003e20 + 7 ms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePower down the chassis layout before executing any attachment or disassembly of modular hardware components.\u003c\/li\u003e\n\u003cli\u003eCarefully align the device along the plastic chassis card guides during initial slot placement.\u003c\/li\u003e\n\u003cli\u003eSum the total current draws of all combined cards to ensure the aggregate loop does not exceed the rated output capacity of the backplane power supply.\u003c\/li\u003e\n\u003cli\u003eKeep the component sealed inside its static-shielded bag until immediately before physical insertion to avoid electrostatic discharge damage.\u003c\/li\u003e\n\u003cli\u003eVerify that the off-state leakage current profile from any integrated 3-wire sensing hardware remains below 3mA.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":52695172940139,"sku":"1771-IB","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0953\/3227\/0443\/files\/allen-bradley-1771-ib-digital-input-module-mgg10fyvtie_bd155a3c-4278-4789-a2e4-10ce406533ea.jpg?v=1766114110","url":"https:\/\/www.plcprotech.com\/de\/products\/allen-bradley-1771-ib-1771-8-point-digital-input-module","provider":"PLC ProTech Ltd.","version":"1.0","type":"link"}
