This module plays a critical role in industrial automation setups by converting physical analog process variables into digital values for the PLC, as well as issuing precise analog control signals to actuators and valves. Built for demanding automation tasks, the 07AI91 ensures high signal fidelity, reliable data acquisition, and consistent loop control across various industrial environments.\u003c\/p\u003e\n\u003cp\u003eDesigned to mount onto standard DIN rails within AC31 rack configurations, this I\/O module interfaces directly with central processing units via the internal system bus. It provides robust electrical isolation between field wiring and internal logic circuits, protecting system electronics from common-mode noise and voltage transients. The unit supports straightforward parameter configuration through the programming environment, enabling fast commissioning and integration into existing AC31 control networks.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eNative compatibility with the ABB AC31 automation and control system product family\u003c\/li\u003e\n  \u003cli\u003eCombined analog input and output channel configuration for versatile process interfacing\u003c\/li\u003e\n  \u003cli\u003eHigh-resolution analog-to-digital and digital-to-analog conversion for accurate loop control\u003c\/li\u003e\n  \u003cli\u003eIntegrated optical isolation protecting internal logic from field-side electrical disturbances\u003c\/li\u003e\n  \u003cli\u003eDIN rail mountable form factor designed for compact control cabinet layouts\u003c\/li\u003e\n  \u003cli\u003eStandardized pluggable terminal blocks for simplified wiring and maintenance\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eIndustrial process control and automation systems\u003c\/li\u003e\n  \u003cli\u003eWater and wastewater treatment facility monitoring\u003c\/li\u003e\n  \u003cli\u003eHVAC and building automation control loops\u003c\/li\u003e\n  \u003cli\u003eManufacturing assembly line data acquisition\u003c\/li\u003e\n  \u003cli\u003eLegacy AC31 system maintenance and expansion\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth\u003eParameter\u003c\/th\u003e\n      \u003cth\u003eSpecification\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\u003eABB\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eProduct Type\u003c\/td\u003e\n      \u003ctd\u003eAnalog I\/O Module\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCatalog \/ Ordering Number\u003c\/td\u003e\n      \u003ctd\u003eGJR5251600R0278\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eModel Designation\u003c\/td\u003e\n      \u003ctd\u003e07AI91\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eProduct Family\u003c\/td\u003e\n      \u003ctd\u003eABB AC31\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCountry of Origin\u003c\/td\u003e\n      \u003ctd\u003eSweden\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eMounting Type\u003c\/td\u003e\n      \u003ctd\u003eDIN Rail\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eDimensions\u003c\/td\u003e\n      \u003ctd\u003e11.8 x 13.6 x 8.3 cm\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eNet Weight\u003c\/td\u003e\n      \u003ctd\u003e0.36 kg\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n  \u003cli\u003eVerify the catalog number and part identity against system documentation before installation.\u003c\/li\u003e\n  \u003cli\u003eDe-energize the entire AC31 rack and associated field power supplies prior to handling hardware.\u003c\/li\u003e\n  \u003cli\u003eInspect the module housing and connector pins for any visible shipping damage or contamination.\u003c\/li\u003e\n  \u003cli\u003eMount the 07AI91 securely onto the standard DIN rail within the designated AC31 system slot.\u003c\/li\u003e\n  \u003cli\u003eConnect field sensors and actuators to the pluggable terminal blocks according to the system wiring diagrams.\u003c\/li\u003e\n  \u003cli\u003eRestore power and configure the I\/O channel parameters using the appropriate ABB programming software.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":52668496347499,"sku":"07AI91","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0953\/3227\/0443\/files\/abb-07ai91-gjr5251600r0278-analog-i-o-module-gups3rthhag_e74d6429-0ad8-4b61-b4a1-f239cf601321.jpg?v=1765532359","url":"https:\/\/www.plcprotech.com\/it\/products\/abb-07ai91-gjr5251600r0278-ac31-analog-i-o-module","provider":"PLC ProTech Ltd.","version":"1.0","type":"link"}
