As part of the 3B34 family, it provides isolated, linearized RTD input with amplification and protective features to shield downstream electronics from sensor-side disturbances. The module supports common RTD configurations—2-, 3-, and 4-wire leads—with a Pt100 temperature range of 0 to +200°C, accommodating the standard Pt100 sensors used in industrial process monitoring. Built-in isolation between the RTD input and the host electronics helps prevent ground loops and improves noise immunity in electrically noisy environments, while the linearization ensures the RTD’s nonlinear resistance-vs-temperature characteristic is presented as a more uniform output for subsequent conversion. Typical applications include temperature monitoring and control in automation systems, HVAC, and process industries, where reliable RTD conditioning and isolation are required before interfacing with PLCs, data loggers, or IPCs. The 3B34-03 module emphasizes safe sensor excitation management and robust protection for the analog input, enabling stable operation across the 0–200°C range without exposing sensitive downstream circuitry to RTD fault conditions.\u003c\/p\u003e\u003c\/div\u003e","brand":"ANALOG","offers":[{"title":"New","offer_id":51659996070190,"sku":null,"price":434.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_71f102e5-e610-405c-b04e-f792c6881d3c.jpg?v=1769531510","url":"https:\/\/plgautomation.com\/products\/analog-devices-3b34-03-isolated-rtd-input-module","provider":"PLG Automation ","version":"1.0","type":"link"}
