XH-W1315 12V DC Digital Thermostat K-Type Thermocouple Controller

The XH-W1315 is a 12V DC digital thermostat module designed for precise temperature measurement and relay-based control in industrial, laboratory, and home environments. It uses a K-type thermocouple probe to measure temperatures from -30°C to 999°C, with 1°C resolution and a measurement accuracy of approximately ±2°C, while the display accuracy is specified at ±1°C. The module provides a single relay output rated for up to 10A, allowing it to switch AC 220V heaters, coolers, and other loads directly. Users configure the thermostat through four front-panel buttons (SET, ENT, +, and -), and the parameter menu includes P0 for heating or cooling mode, P1 for hysteresis, P2 for temperature correction, and P3 for a high-temperature alarm. The seven-segment LED display shows the real-time temperature, and the compact board measures 79 × 54 × 21 mm and weighs approximately 60 g. This temperature controller module is suitable for incubators, ovens, soldering stations, freezers, and any system that requires an adjustable, relay-driven thermal control loop. As a 12V digital thermostat with a K-type thermocouple controller, the XH-W1315 combines a wide measurement range with straightforward button-based programming for both prototyping and permanent installations.
