The W1209 is a digital temperature controller module designed for precise heating and cooling control in automation projects, incubators, and temperature-regulated environments. This compact controller intelligently manages power to electrical devices based on accurate temperature readings.
Key Features:
- Operating Voltage: Works on a 12V DC power supply.
- Wide Temperature Range: Measures and controls temperatures from -50°C to 110°C.
- High Accuracy: Offers a measurement and control accuracy of 0.1°C.
- 3-Digit Display: Features a clear and bright display for real-time temperature readings and settings.
- Robust Relay Specifications:
- Handles up to 125V AC or 14V DC at 20A.
- Supports up to 240V AC at 5A or 14V DC at 10A.
- NTC Temperature Sensor: Comes with a waterproof NTC 10K thermistor with a 0.5-meter cable, ensuring precise temperature sensing in various conditions.
- Compact Design: Dimensions of 48mm x 40mm x 14mm, allowing for easy integration into different projects.
Functionality:
The W1209 module is equipped with customizable settings that make it adaptable for a variety of applications:
- P0 (Heating/Cooling Mode): Choose whether the relay is energized or de-energized when the set temperature is reached.
- P1 (Hysteresis): Define the temperature difference between the relay’s ON and OFF states for precise control.
- P2 and P3: Set the maximum and minimum temperature limits.
- P4: Adjust for temperature correction or calibration.
- P5 (Start Delay): Implement a delay of 0 to 10 minutes before the relay activates.
- P6 (Alarm Mode): Activate a high-temperature alarm, which deactivates the relay and displays an alert when a set temperature is reached.
Easy Configuration:
- Simple Controls: Configure settings using three buttons: SET, +, and -. Long-pressing the SET button grants access to programmable settings.
- Non-Volatile Memory: Settings are stored in memory, ensuring they are retained even after the module is powered off.
Applications:
The W1209 is suitable for a wide range of uses, including:
- Automation Projects: Control devices based on precise temperature measurements.
- Incubators: Maintain stable temperatures crucial for hatching.
- Temperature-Controlled Environments: Ideal for greenhouses, aquariums, or any environment requiring strict temperature regulation.
