Description
The W1209 is a compact 12V DC thermostat module for switching a heater, fan or other suitable load according to the measured temperature. Its three-digit LED display shows the sensor reading, while three buttons provide access to the target temperature and controller settings.
A wired 10 kΩ NTC probe allows the module to measure away from the board. It can be configured for heating or cooling control, making it useful for incubators, small enclosures, cooling fans, fermentation projects and other DIY temperature-control applications. The connected load must stay within the ratings printed on the supplied relay and should be installed with appropriate electrical protection.
Why you’ll love it
- Heating or cooling control: Configure the relay to switch a suitable heater or cooling device.
- Remote temperature sensing: The wired NTC probe can be positioned inside the area being monitored.
- Clear local display: View the measured temperature and adjust the setpoint from the board.
- Adjustable switching behaviour: Set the hysteresis to prevent rapid relay cycling around the target temperature.
- Compact DIY module: Fits small control panels, prototypes and enclosure projects.
