Description
The XH-W1209 is a compact digital temperature control module equipped with an LED display and an onboard 10A switching relay. It accurately measures and regulates temperatures between -50°C and +110°C using an external waterproof NTC probe. This unit is well suited to hobbyists, students and makers building automated heating or cooling setups.
Automated temperature regulation
The module provides ON/OFF switching control across a -50°C to +110°C range with 0.1°C control and hysteresis accuracy. It features high temperature protection settings up to 110°C and refreshes its reading every 0.5 seconds.
Power and relay output
Powered by a 12V DC supply, the board draws 35mA or less in static mode and up to 65mA when the relay is engaged. The onboard relay supports switching loads up to 10A.
Sensor and physical dimensions
The controller measures 48 x 40mm and connects to an included 10K 0.5% waterproof NTC temperature sensor on a roughly 52cm lead. It operates reliably in ambient environments from -10°C to 60°C with 20% to 85% humidity.
