It provides up to 16 channels of galvanically isolated signal conditioning and supplies 24 VDC power to energize loop devices, ensuring safe signal transmission across TDC 2000, TDC 3000, and Experion PKS architectures.\u003c\/p\u003e\n\u003ch3\u003eFunctional Role and System Integration\u003c\/h3\u003e\n\u003cp\u003eThis module acts as a protective interface designed for use with high-level analog input (HLAI) and smart transmitter (STI) Field Termination Assemblies (FTAs). By providing galvanic isolation, it prevents ground loops and blocks hazardous voltages from transferring into sensitive control system electronics, supporting up to 16 input channels within a B series form factor measuring 307 mm (12.1 inches) in length.\u003c\/p\u003e\n\u003ch3\u003eElectrical and Safety Characteristics\u003c\/h3\u003e\n\u003cp\u003eThe unit operates on a typical 24 VDC power supply and delivers sufficient DC output to energize connected 4-20 mA transmitters. It handles critical electrical boundary conditions with a maximum open-circuit voltage of 28 VDC, a minimum source resistance of 300 ohms, a maximum short-circuit current of 93 milliamps, and a maximum applied voltage rating of 250 Vrms.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\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\u003eModel Number\u003c\/td\u003e\n\u003ctd\u003e51191697-200\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer\u003c\/td\u003e\n\u003ctd\u003eHoneywell\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eGalvanic Isolation Module (MTL4041B)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSystem Compatibility\u003c\/td\u003e\n\u003ctd\u003eHoneywell DCS (TDC 2000, TDC 3000, Experion PKS)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChannels\u003c\/td\u003e\n\u003ctd\u003eUp to 16\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIsolation Type\u003c\/td\u003e\n\u003ctd\u003eGalvanically isolated\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDC Power Output\u003c\/td\u003e\n\u003ctd\u003eEnergizes 4-20 mA transmitters (24 VDC typical)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax Open-Circuit Voltage\u003c\/td\u003e\n\u003ctd\u003e28 Vdc\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMin Source Resistance\u003c\/td\u003e\n\u003ctd\u003e300 ohms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax Short-Circuit Current\u003c\/td\u003e\n\u003ctd\u003e93 milliamps\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax Applied Voltage\u003c\/td\u003e\n\u003ctd\u003e250 Vrms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003eB series (307 mm \/ 12.1 inches)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003cp\u003eFrequently Asked Questions\u003c\/p\u003e\n\u003cp\u003eQ: Which field termination assemblies are compatible with the Honeywell 51191697-200 module?\u003c\/p\u003e\n\u003cp\u003eA: This module is specifically designed for use with high-level analog input (HLAI) and smart transmitter (STI) Field Termination Assemblies.\u003c\/p\u003e\n\u003cp\u003eQ: What power and signal functions does the module provide for field instruments?\u003c\/p\u003e\n\u003cp\u003eA: It provides galvanic isolation while delivering 24 VDC power to energize standard 4-20 mA transmitters connected to the system.\u003c\/p\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":68137082847528,"sku":"51191697-200","price":315.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0827\/6266\/2184\/files\/51196895-100_d4feed36-a5a5-436e-9b44-e9d547a427cf.png?v=1794216168","url":"https:\/\/www.powerdcs.com\/ar\/products\/honeywell-51191697-200-galvanic-isolation-module","provider":"Power DCS Parts Limited","version":"1.0","type":"link"}
