5V Thermal Sensor 1Ch Relay Module Thermistor Temperature Sensor Module

use:

Temperature detection, adjust to a certain valve point through the potentiometer, control the corresponding temperature, with relay output, directly connect AC high-power products.

Module features:

1. Automatically control the temperature, start below the temperature, or start above the temperature. Select to start higher than the set temperature when the output terminal is normally open, and start normally when the output is lower than the set temperature;

2. The comparator output directly drives the relay, which can be connected to 220V AC or other equipment;

3. With potentiometer to adjust the temperature;

4. The sensor interface can be equipped with a pin and a thermal sensor with a lead;

5. Dimensions: 50x26mm, 19mm thick, with 4 3mm fixing bolt holes for easy installation.

Electrical parameters:

Supply voltage: 5VDC

Current: greater than 150mA

Load: 250V 10A AC or 30V 10A DC

Module instructions:

1. The thermistor module is most sensitive to the ambient temperature. It is generally used to detect the temperature of the surrounding environment. The replacement of the waterproof type thermal sensor can detect the water temperature.

2. When the ambient temperature exceeds the set threshold, the relay is closed, and the common end is connected to the normally open end. When the ambient temperature is lower than the set threshold, the relay is disconnected, and the common end is connected to the normally closed end;

3. Common end, normally open, normally closed three ports are equivalent to a dual control switch. When the relay coil is energized, the common end is electrically connected to the normally open end. When there is no electricity, the common end and the normally closed end are turned on;
