This module features 8 differential input channels capable of processing both millivolt signals and a wide range of thermocouple types, providing reliable temperature and low-voltage monitoring for critical industrial processes.\u003c\/p\u003e\u003ch3\u003eTechnical Description\u003c\/h3\u003e\u003cp\u003eThe AI835A provides versatile signal conditioning with configurable measurement ranges for each channel. It supports linear inputs from -30 mV to +75 mV, as well as a comprehensive list of thermocouple standards including types B, C, D, E, J, K, L, N, R, S, T, and U. For temperature compensation, Channel 8 can be configured as a Cold Junction (CJ) channel, allowing for ambient temperature measurement via a Pt100 RTD sensor. This sensor can be mounted directly on the module's Module Termination Unit (MTU) or located at a remote connection point. If CJ compensation is not required, Channel 8 may be utilized as a standard differential input.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e8 differential input channels for thermocouple and mV signals.\u003c\/li\u003e\n\u003cli\u003eHigh-precision 15-bit A\/D resolution for accurate process monitoring.\u003c\/li\u003e\n\u003cli\u003eComprehensive thermocouple support: B, C, D, E, J, K, L, N, R, S, T, and U.\u003c\/li\u003e\n\u003cli\u003eIntegrated wire-break and open-circuit detection for enhanced diagnostic capability.\u003c\/li\u003e\n\u003cli\u003eGroupwise isolation from ground to ensure signal integrity.\u003c\/li\u003e\n\u003cli\u003eConfigurable Cold Junction compensation via Channel 8.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eAI835A (3BSE051306R1)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChannels\u003c\/td\u003e\n\u003ctd\u003e8 Differential\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eResolution\u003c\/td\u003e\n\u003ctd\u003e15 bits\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Impedance\u003c\/td\u003e\n\u003ctd\u003e\u0026gt; 1 MΩ\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax Cable Length\u003c\/td\u003e\n\u003ctd\u003e600 meters\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCMRR (50\/60Hz)\u003c\/td\u003e\n\u003ctd\u003e120 dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNMRR (50\/60Hz)\u003c\/td\u003e\n\u003ctd\u003e\u0026gt; 60 dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Dissipation\u003c\/td\u003e\n\u003ctd\u003e1.6 W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIsolation\u003c\/td\u003e\n\u003ctd\u003eGroupwise isolated\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRated Insulation\u003c\/td\u003e\n\u003ctd\u003e50 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eEnsure all power is disconnected from the I\/O rack before inserting or removing the AI835A module.\u003c\/li\u003e\n\u003cli\u003eUse shielded twisted-pair cabling for all field inputs to minimize EMI interference; ensure shields are properly grounded at the designated termination points.\u003c\/li\u003e\n\u003cli\u003eMaintain proper ventilation within the cabinet to stay within operating temperature limits.\u003c\/li\u003e\n\u003cli\u003eVerify that the MTU (Module Termination Unit) is correctly installed and wired before seating the module.\u003c\/li\u003e\n\u003cli\u003eHandle with care to prevent electrostatic discharge (ESD) damage during installation.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eApplications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePower Generation: Boiler temperature monitoring, exhaust gas analysis, and turbine diagnostics.\u003c\/li\u003e\n\u003cli\u003eChemical \u0026amp; Petrochemical: Reactor temperature control and fluid line monitoring.\u003c\/li\u003e\n\u003cli\u003eOil \u0026amp; Gas: Remote extraction site data acquisition and refinery process monitoring.\u003c\/li\u003e\n\u003cli\u003eWater \u0026amp; Wastewater: Climate tracking and liquid process management.\u003c\/li\u003e\n\u003cli\u003eMetallurgy: Furnace, casting, and curing temperature regulation.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch3\u003eWhat is the primary function of the AI835A module?\u003c\/h3\u003e\u003cp\u003eThe AI835A is an analog input module designed to interface thermocouple and millivolt sensors with the ABB S800 I\/O system, primarily for accurate temperature measurement in industrial automation environments.\u003c\/p\u003e\u003ch3\u003eCan Channel 8 be used for standard inputs?\u003c\/h3\u003e\u003cp\u003eYes, if Cold Junction (CJ) compensation is not required, Channel 8 can be configured to function as a standard differential input channel just like channels 1 through 7.\u003c\/p\u003e\u003ch3\u003eIs this module compatible with HART communication?\u003c\/h3\u003e\u003cp\u003eNo, the AI835A does not support HART communication or Sequence of Events (SOE) time-tagging.\u003c\/p\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":44019895861338,"sku":"3BSE051306R1","price":120.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/5957\/0778\/files\/wm_1_9fe1f26f-9236-49e8-92d1-05e9049523fc.jpg?v=1788669643","url":"https:\/\/www.spareoil.com\/es\/products\/abb-ai835a-3bse051306r1-thermocouple-mv-input-module","provider":"SpareOil Automation","version":"1.0","type":"link"}
