XY-DT01 30A LCD Digital Temperature Controller – 6V-30V DC with DS18B20 & 50K NTC Sensor, Relay Thermostat Switch for Precise Thermal Regulation

Description

Description

The XY-DT01 30A LCD Digital Temperature Controller is a professional-grade, highly versatile thermostat designed for precise thermal regulation across a wide range of applications. Operating on a broad DC voltage range of 6V to 30V, this controller is compatible with automotive systems (12V), industrial PLC panels (24V), solar battery banks, and many other DC power sources commonly found in residential, commercial, and industrial environments .

At the heart of this module is a powerful 30A relay, capable of switching high-current loads up to 30A at 220V AC or 30A at 30V DC, making it suitable for controlling refrigerators, incubators, fermenters, greenhouse heaters, industrial pumps, and other heavy-duty equipment . Unlike smaller relay modules that require external contactors for high-power loads, the XY-DT01 can drive many devices directly.

The controller features a bright, high-definition LCD display that shows real-time temperature readings with 0.1°C precision . Four tactile buttons provide intuitive access to all programmable parameters, including set temperature, hysteresis (return difference), alarm thresholds, delay start, and temperature calibration.

A key differentiator of the XY-DT01 is its dual sensor compatibility. The module ships with a waterproof NTC 50K thermistor probe (cable length 50cm) and also supports the DS18B20 digital temperature sensor (not included) for applications requiring higher accuracy or longer cable runs . Users can select their preferred sensor type via the configuration menu.

The controller offers both Heating Mode (‘H’) and Cooling Mode (‘C’) , selectable via the settings menu. In Heating Mode, the relay activates when the measured temperature falls below the setpoint minus hysteresis, and deactivates when the setpoint is reached. Cooling Mode operates inversely, activating when temperature exceeds the setpoint plus hysteresis .

Advanced features include a programmable high-temperature alarm (ALA) with audible and visual indicators, an adjustable delay start (OPH) to prevent short-cycling of compressors or heaters, and a temperature correction offset (OFE) to calibrate the displayed temperature against a reference thermometer .

The controller is housed in a compact, industrial-grade enclosure (88 x 55 x 44mm) featuring a standard 35mm DIN rail mounting capability, allowing for easy installation inside electrical panels, control cabinets, and equipment enclosures . The screw terminal blocks provide secure, vibration-resistant connections for power input, sensor input, and relay output.

Important Operational Note: The XY-DT01 is a relay output controller and does NOT supply power to connected loads. The relay contacts are voltage-free (dry contacts), meaning the user must provide a separate power supply for the heating or cooling equipment. This design ensures maximum flexibility and safety across different voltage systems .

Whether you need to maintain precise temperatures in a reptile incubator, automate greenhouse ventilation, protect a server room from overheating, control a home brewing fermentation chamber, or manage industrial refrigeration, the XY-DT01 delivers accurate, reliable, and programmable temperature regulation in a professional, easy-to-use package.
