This module is specifically engineered to interface with thermocouple and millivolt (mV) sensors, providing reliable data acquisition for critical process monitoring in demanding industrial environments, including power generation, petrochemical refining, and metallurgy. It supports high-resolution temperature sensing to help maintain process stability and minimize downtime.\u003c\/p\u003e\u003ch3\u003eHardware Interface and Safety Architecture\u003c\/h3\u003e\u003cp\u003eThe KJ3002X1-BG2 features energy-limiting circuitry designed for use in Zone 2 hazardous atmospheres. It incorporates a mechanical rotary keying system, requiring the associated terminal block to be set to position B2 to ensure correct hardware compatibility. The module supports Removal and Insertion Under Power (RIUP) when used with compatible DeltaV power supplies, provided that primary circuit inductance is managed appropriately. Field power should be disconnected at the terminal level prior to physical extraction to maintain circuit integrity.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e8-channel isolated input for thermocouple and millivolt signals.\u003c\/li\u003e\n\u003cli\u003eDesigned for ISA-S71.04-1985 Class G3 harsh environment compliance.\u003c\/li\u003e\n\u003cli\u003eSupports RIUP (Removal and Insertion Under Power) for modular maintenance.\u003c\/li\u003e\n\u003cli\u003eIntegrated mechanical keying (Position B2) to prevent incorrect module insertion.\u003c\/li\u003e\n\u003cli\u003eFactory calibrated for high precision; no field calibration required.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eApplications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eTemperature monitoring in petrochemical and chemical processing.\u003c\/li\u003e\n\u003cli\u003eHigh-accuracy millivolt signal acquisition for industrial automation.\u003c\/li\u003e\n\u003cli\u003eCritical process control in power generation facilities.\u003c\/li\u003e\n\u003cli\u003eHarsh environment sensing where G3-rated equipment is mandatory.\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\u003eKJ3002X1-BG2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003e12P1731X082\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Types\u003c\/td\u003e\n\u003ctd\u003eThermocouple, Millivolt (mV)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLocalBus Power\u003c\/td\u003e\n\u003ctd\u003e12 VDC at 350 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eField Circuit Rating\u003c\/td\u003e\n\u003ctd\u003e5.5 VDC at 0.6 mA per channel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e0 to 60 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRelative Humidity\u003c\/td\u003e\n\u003ctd\u003e5 to 95% Non-Condensing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIngress Protection\u003c\/td\u003e\n\u003ctd\u003eIP 20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTerminal Keying\u003c\/td\u003e\n\u003ctd\u003ePosition B2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShock Resistance\u003c\/td\u003e\n\u003ctd\u003e10g 1\/2 Sinewave for 11 msec\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVibration Resistance\u003c\/td\u003e\n\u003ctd\u003e1mm P-P (5-16Hz); 0.5g (16-150Hz)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAirborne Contaminants\u003c\/td\u003e\n\u003ctd\u003eISA-S71.04-1985 Class G3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eEnsure the terminal block is keyed to position B2 before module installation.\u003c\/li\u003e\n\u003cli\u003eVerify that the system power supply supports RIUP functionality for the specific rack configuration.\u003c\/li\u003e\n\u003cli\u003eAlways disconnect field power at the terminal level before removing the module to ensure safety in hazardous areas.\u003c\/li\u003e\n\u003cli\u003eHandle with care to prevent ESD damage; use a grounded wrist strap during installation.\u003c\/li\u003e\n\u003cli\u003eEnsure adequate ventilation in the cabinet to maintain ambient temperatures within the 0 to 60 deg C range.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCompliance and Certifications\u003c\/h3\u003e\u003cp\u003eThe module is certified for use in Zone 2 hazardous areas (II 3 G, EEx nL IIC T4) per Nemko 02ATEX431U.\u003c\/p\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eIs field calibration required for this module?\u003c\/strong\u003e\u003cbr\u003eNo, the KJ3002X1-BG2 is factory calibrated and does not require field calibration.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan this module be removed while the system is powered?\u003c\/strong\u003e\u003cbr\u003eYes, it supports RIUP (Removal and Insertion Under Power), provided that field power is disconnected at the terminal block and system inductance requirements are met.\u003c\/p\u003e","brand":"Emerson","offers":[{"title":"Default Title","offer_id":50619400618236,"sku":"KJ3002X1-BG2 12P1731X082","price":89.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0787\/9983\/1292\/files\/wm_1_d9097548-4972-4e4c-af5e-943ca7e67e21.jpg?v=1784870751","url":"https:\/\/www.electronicplc.com\/products\/emerson-deltav-kj3002x1-bg2-12p1731x082","provider":"Electronic PLC","version":"1.0","type":"link"}
