  • Photodiode Relay Control Module

     

    Purpose:

     

    Light detection, brightness detection, adjustable detection brightness valve point through potentiometer, built-in relay, various brightness detection switches, can control various street lights, automatically turn on at night, automatically turn off during the day, and vehicle supplies control and automation equipment.

     

    (Compared with photosensitive resistor, it has good directionality. It can sense the light source in a fixed direction and detect the light directly in front of the photosensitive diode. It is difficult to detect the surrounding area, and it is often applied to the light-seeking function)

     

    Module Features:

     

    1. The photosensitive diode is used to sense the intensity of the light, with its own relay to directly control the load

    2. It is equipped with a potentiometer to adjust the sensitivity. By adjusting the potentiometer, the threshold value of the starting relay is set. When the threshold value is on, the module relay is closed, and when the threshold value is dark, the relay is released. Therefore, connecting the normally open and common end is the switch that controls the day, and connecting the normally closed and common end is the switch that controls the night.

    3. Working voltage 5V

    4. Output mode: directly connected to AC 220V 10A or DC30V 10A load

    5. There are 4 fixing bolt holes for easy installation

    6. Small PCB size: 5cm x 2.6cm

    7. Use wide voltage LM393 comparator

     

    Electrical Parameters:

     

    ● Power supply voltage: 5VDC

    ● Current: more than 100mA

    ● Load: 250V 10A AC or 30V 10A DC

     

    Module Instructions:

     

    1. Photodiodes are the most sensitive to ambient light, and are generally used to detect the brightness of ambient light.

    2. When the ambient light of the module exceeds the set threshold, the relay is closed and the common end and the normally closed end are connected. When the ambient light of the module is lower than the set threshold, the relay is disconnected and the common end and the normally closed end are connected;

    3. The three ports of common end, normally open and normally closed are equivalent to a dual-control switch. When the relay coil is powered on, the common end and normally closed end are connected. When there is no power, the common end and normally closed end are connected
