Use:

Various flame, fire source detection, relay output, can be connected to 220V high current equipment appliances

Module Features:

1. It can detect flames or light sources with wavelengths ranging from 760 nm to 1100 nm. The lighter test flame distance is 80cm. The larger the flame, the farther the test distance
2. The detection angle is about 60 degrees, which is particularly sensitive to the flame spectrum.
3. Adjustable sensitivity (adjusted by blue digital potentiometer in the figure)
4.The comparator output directly triggers the relay
5. Dimensions: 50x26mm, thickness 19mm, with fixing bolt holes for easy installation
6. Output with blue terminal block, convenient wiring

Electrical parameters:

Power supply voltage: 12VDC
Current: greater than 150mA
Load: 250V 10A AC or 30V 10A DC

Module use instructions:

1. The flame sensor is the most sensitive to flames and also responds to sunlight. It is generally used for flame alarms and other purposes.
2. By adjusting the potentiometer, you can set the intensity of the sensor to sense the flame. When the flame exceeds the set threshold, the relay will pull in, and the common end will be connected to the normally open end. The public terminal is connected to the normally closed terminal;
3. The common terminal is normally open. The normally closed three ports are equivalent to a dual control switch. When the relay coil is energized, the common terminal is connected to the normally open terminal. When there is no power, the common terminal is connected to the normally closed terminal.
4. Keep a certain distance between the sensor and the flame to avoid damage to the sensor due to high temperature. The flame distance for the lighter test is 80cm. The larger the flame, the farther the test distance is.
