It accepts an RTD sensor input and measures temperatures from -212 degrees C up to 2500 degrees F, making it suitable for high-temperature process environments. The controller uses PID control logic to regulate temperature output and delivers a 4 to 20 mA isolated analog output signal for integration with downstream control systems or data acquisition equipment. A dual 4-digit LCD display with dual 0.56-inch scale provides clear readout of process and setpoint values simultaneously. Licensed HVAC technicians, process control engineers, and industrial instrumentation specialists are the primary installers.\u003c\/p\u003e\u003cp\u003eThe DWYER 25025 is used in industrial process heating, commercial HVAC controls, and manufacturing environments where precise temperature regulation is required. The wide input voltage range of 100 to 240 volts makes it compatible with both domestic and international power configurations. Its quarter-DIN panel-mount form factor fits standard instrument cutouts commonly found in control panels and equipment enclosures. RTD sensor input suits applications where high accuracy and stability over a wide temperature span are priorities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePID control type for accurate, stable temperature regulation\u003c\/li\u003e\n\u003cli\u003eRTD sensor input with measurement range up to 2500 degrees F (1371 degrees C)\u003c\/li\u003e\n\u003cli\u003e4 to 20 mA isolated analog output for system integration\u003c\/li\u003e\n\u003cli\u003eDual 4-digit LCD display with dual 0.56-inch scale for simultaneous process and setpoint readout\u003c\/li\u003e\n\u003cli\u003eWide supply voltage range: 100 to 240 volts AC\u003c\/li\u003e\n\u003cli\u003eQuarter-DIN panel-mount form factor for standard instrument enclosures\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation quarter-DIN temperature controller for industrial control panels and process equipment that use RTD sensors and accept a 4 to 20 mA control signal output.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified instrumentation technician or licensed electrician familiar with panel-mounted process controls. Disconnect and lock out all power to the control panel before mounting or wiring the controller. Follow applicable NEC guidelines for control wiring in industrial enclosures. Verify RTD sensor wiring configuration and signal loop connections before energizing the system.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSensor Input\u003c\/strong\u003e: RTD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eControl Type\u003c\/strong\u003e: PID\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Temperature\u003c\/strong\u003e: -212 degrees C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 2500 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput\u003c\/strong\u003e: 4 to 20 mA Isolated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisplay Type\u003c\/strong\u003e: Dual 4-Digit LCD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisplay Scale\u003c\/strong\u003e: Dual 0.56 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Supply Voltage\u003c\/strong\u003e: 100 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Supply Voltage\u003c\/strong\u003e: 240 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eForm Factor\u003c\/strong\u003e: Quarter DIN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.75 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: DWYER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 25025\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DWYER","offers":[{"title":"Default Title","offer_id":51543406477618,"sku":"25025","price":2197.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/06391546de6d6e3c13f1d6ef336cb4c5_dc579096-f6db-4f7f-9ddc-de279123af88.jpg?v=1785918047","url":"https:\/\/voomisupply.com\/products\/dwyer-25025-quarter-din-temperature-controller-rtd-pid","provider":"Voomi Supply","version":"1.0","type":"link"}
