It provides 16.5 V transmitter power and repeats the signal to the safe area. The “B” version is adapted for direct substitution of legacy MTL4041B modules on existing backplanes.\u003c\/p\u003e\n\u003ch3\u003eKey Specs\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eChannels: 1\u003c\/li\u003e\n\u003cli\u003eSignal: 0–24 mA (4–20 mA nominal) with HART\u003c\/li\u003e\n\u003cli\u003eTransmitter supply: 16.5 V at 20 mA\u003c\/li\u003e\n\u003cli\u003eSafe-area load: Up to 450 Ω @ 20 mA class\u003c\/li\u003e\n\u003cli\u003eAccuracy: ±15 µA at 20 °C class\u003c\/li\u003e\n\u003cli\u003eLegacy compatibility: Adapted for MTL4041B substitution\u003c\/li\u003e\n\u003cli\u003eMounting: MTL4500 backplane\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhy Choose This\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSingle-channel HART-compatible isolator\u003c\/li\u003e\n\u003cli\u003ePowers hazardous-area transmitters\u003c\/li\u003e\n\u003cli\u003eDirect replacement path for MTL4041B installations\u003c\/li\u003e\n\u003cli\u003eCertified for Zone 0 \/ Div 1 applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCommon Questions\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eChannels?\u003c\/strong\u003e 1.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHART?\u003c\/strong\u003e Yes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLegacy?\u003c\/strong\u003e Compatible with MTL4041B backplanes.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eMounting Steps\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eInstall the module on the compatible backplane.\u003c\/li\u003e\n\u003cli\u003eWire the hazardous-area transmitter and safe-area load.\u003c\/li\u003e\n\u003cli\u003eConnect system power.\u003c\/li\u003e\n\u003cli\u003eVerify loop current and HART communication.\u003c\/li\u003e\n\u003cli\u003eConfirm isolation and status.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003ch3\u003eBuying Advice\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eChoose for single-channel HART transmitter isolation or MTL4041B replacement.\u003c\/li\u003e\n\u003cli\u003eConfirm backplane and load requirements.\u003c\/li\u003e\n\u003cli\u003eUseful spare for MTL4500 \/ legacy isolator positions.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Emerson","offers":[{"title":"Default Title","offer_id":50404521377930,"sku":"MTL4541B","price":202.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0698\/2818\/2154\/files\/MTL4541B_2_95005306-400f-47ec-a035-c51f50c421b1.jpg?v=1791613071","url":"https:\/\/www.cambiaplc.com\/products\/single-channel-hart-isolator-mtl4541b-4-20ma","provider":"Controlix Automation","version":"1.0","type":"link"}
