Product Features: The product is compact and easy to carry. 2. It is simple to use and easy to operate. 3. Long service life and reliable quality. 4. Excellent quality, exquisite workmanship and fine materials. 5. It has wide applications and can be used in multiple scenarios. Product parameters: Name: Relay Temperature Controller Voltage: 12V The maximum load capacity of the normally open interface: AC 0V- 250V/10A, DC 0V- 30V/10A Fixing bolt holes: 4 Module size: 5.0cm/3.0cm/1.8cm Packaging list: 12V relay temperature controller /1 I. Functional Features: 1. It adopts highly sensitive thermistors to detect the ambient temperature and is equipped with genuine high-quality relays. It can directly control AC or DC loads. The maximum load capacity of the normally open interface: AC 0V- 250V/10A, DC 0V- 30V/10A. 2. The temperature threshold can be adjusted through a potentiometer. When the ambient temperature is higher than this threshold, the relay is engaged; when the temperature is lower than this threshold, the relay is released 3. Intelligent regulation design: After the relay operates, it automatically fine-tunes the action threshold, solving the problem of repeated actions of the critical value. 4. The module has an anti-reverse connection function. Reversing the power supply will not damage the module. 5. Equipped with power indicator light red and relay status indicator light red 6. The working voltage of the module is available in 5V, 12V and 24V. Please be sure to specify when purchasing. 7. It is equipped with 4 fixed bolt holes compatible with convenient installation. 8. Module size: 5.0cm/3.0cm/1.8cm 9. The module comes with a thermal sensor with a 30CM lead compatible with free. Ii. Instructions compatible with Use: The thermistor module is sensitive to the ambient temperature and is generally used to detect changes in the surrounding environment/x27;s temperature. 2. When the ambient temperature of the module is higher than the set threshold, the relay is engaged and the common terminal is connected to the normal terminal disconnected from the normally closed terminal . When the external ambient temperature is lower than the set threshold, the relay is disconnected and the common terminal is disconnected from the normal terminal connected to the normally closed terminal . 3. The common terminal, normally open, and normally closed ports are equivalent to a dual-control switch. When the relay coil is energized, the common terminal conducts with the normally open terminal; when it is not energized, the common terminal conducts with the normally closed terminal. Iii. Electrical Parameters: Working voltage: DC 5V, 12V or 24V are available compatible with selection Working current: After the relay is engaged: 5V module less than 90mA, 12V module less than 50mA, 24V less than 20mA Before the relay is engaged: less than 5mA Load capacity: AC 0V- 250V/10A, DC 0V- 30V/10A;
