KNACRO 12V SRD-12VDC-SL-A 2-Channel Flame Sensor Relay Module Infrared Photoelectric Receiver Tube Sensor Relay Module

1, can detect the flame or wavelength in the range of 760 nm to 1100 nm light source, lighter test flame distance of 80cm, the greater the flame, the longer the test distance. 2, the detection angle of about 60 degrees, particularly sensitive to the flame spectrum. 3, the sensitivity is adjustable (blue digital potentiometer adjustment). 4, the comparator output directly trigger the relay. 5, with four fixed bolt holes, easy to install. 6, 2 output with blue terminal block, easy wiring. Electrical parameters: Supply voltage: 12VDC Current: ?200mA Load: 250V 10A AC or 30V 10A DC Module instructions: 1, the flame sensor is most sensitive to the flame, the sun is also a reaction, generally used for flame alarm and other purposes. 2, by adjusting the potentiometer, you can set the sensor to detect the intensity of the flame, when the sensor senses the intensity of the flame exceeds the set threshold, the relay pull, the relay switch connected, when the sensor senses the flame strength is lower than the set Threshold, the relay is off, the relay switch off; 3, the sensor and the flame to maintain a certain distance, so as not to damage the sensor at high temperatures, the flame test flame distance of 80cm, the greater the flame, the longer the test distance. Package Included? 1*2-Channel Flame Sensor Relay Module
