It uses \u003c\/span\u003e\u003cstrong\u003e\u003cspan\u003ePt-100 RTD sensors\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e to continuously monitor the temperature of the three transformer windings and an additional critical point such as the core. The relay provides four independent relay outputs for \u003c\/span\u003e\u003cstrong\u003e\u003cspan\u003ecooling fan control, high-temperature alarm, very-high-temperature trip, and sensor\/fault indication\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e, helping prevent overheating and potential transformer damage. It also supports maximum-temperature memory and, depending on the variant, a \u003c\/span\u003e\u003cstrong\u003e\u003cspan\u003e4–20 mA analog output or RS-485 Modbus RTU communication\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e for remote monitoring. With its programmable set points, reliable temperature monitoring, and rugged industrial design, the TR-7570 is well suited for transformer protection and control applications.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Krishna Machinery Tools","offers":[{"title":"Default Title","offer_id":55942607470665,"sku":null,"price":0.0,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0974\/8250\/6313\/files\/TR-7570transformerprotectionrelay.jpg?v=1787552738","url":"https:\/\/kmtimpex.com\/products\/tr-7570-transformer-protection-relay","provider":"Krishna Machinery Tools","version":"1.0","type":"link"}
