It accepts a universal sensor input, making it compatible with a wide range of thermocouples and RTDs without requiring a dedicated input module. The controller operates on 100 to 240 volts AC, features fuzzy logic PID control for stable and responsive temperature regulation, and displays readings on a dual 4-digit LCD with a 0.56-inch scale. A built-in alarm output and mechanical relay output round out the core functionality. Licensed HVAC technicians and industrial controls specialists are the typical installers.\u003c\/p\u003e\u003cp\u003eThis controller fits quarter DIN panel cutouts and is suited for residential and light commercial process control panels, boiler management systems, industrial ovens, and temperature monitoring stations. It handles a measurement range extending up to 4208 degrees F, making it applicable across low- and high-temperature process environments. The universal sensor input reduces stocking complexity by accommodating multiple sensor types within a single unit. Where a compact, panel-mount temperature controller with PID and alarm capability is required, the 26133 is a direct-fit solution.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eUniversal sensor input accepts multiple thermocouple and RTD types\u003c\/li\u003e\n\u003cli\u003eFuzzy logic PID control for accurate and stable temperature regulation\u003c\/li\u003e\n\u003cli\u003eDual 4-digit LCD display with 0.56-inch digit scale for easy readback\u003c\/li\u003e\n\u003cli\u003eWide supply voltage range: 100 to 240 volts AC\u003c\/li\u003e\n\u003cli\u003eIntegrated alarm output for setpoint deviation notification\u003c\/li\u003e\n\u003cli\u003eMechanical relay output for direct load or external device switching\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation controller for quarter DIN panel cutouts in temperature and process control applications requiring universal sensor input.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified controls technician or licensed electrician familiar with NEC panel wiring requirements. Power down the control panel completely before wiring or removing an existing controller. Verify sensor type and wiring polarity before energizing to avoid input errors or sensor damage. Consult the manufacturer wiring diagram for relay output and alarm terminal assignments prior to commissioning.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Quarter DIN Temperature and Process Controller\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSensor Input\u003c\/strong\u003e: Universal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 4208 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Temperature\u003c\/strong\u003e: -17 degrees C\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\u003eDigit Scale\u003c\/strong\u003e: 0.56 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eControl Type\u003c\/strong\u003e: Fuzzy Logic PID\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput\u003c\/strong\u003e: Mechanical Relay\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAlarm\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Voltage\u003c\/strong\u003e: 100 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Voltage\u003c\/strong\u003e: 240 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.3 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: 26133\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DWYER","offers":[{"title":"Default Title","offer_id":51538991350066,"sku":"26133","price":1311.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f48dfaec6e9329a5eff2f547adc85691.jpg?v=1785832041","url":"https:\/\/voomisupply.com\/products\/dwyer-26133-quarter-din-temperature-process-controller","provider":"Voomi Supply","version":"1.0","type":"link"}
