Description

Features:
1. It adopts photoresistor to sense the intensity of light, and comes with a genuine high-quality relay, which can directly control AC or DC load. The maximum load capacity of the normally open interface: AC 0V-250V/10A, DC 0V–30V/10A;
2. The sensitivity can be adjusted by the potentiometer, and the threshold value of the start relay can be set by adjusting the potentiometer. When it is darker than this threshold, the module relay is closed, and when it is brighter than this threshold, the relay is released; intelligent adjustment design, when the relay is activated , Automatically fine-tune the action threshold, which solves the problem of repeated actions at the critical value;
3. The module has the function of anti-reverse connection, and the reverse connection of the power supply will not damage the module;
4. Equipped with power indicator (red) and relay status indicator (blue)
5. There are 4 fixing bolt holes for easy installation;
6. Module size: 5.0cm*3.0cm*1.8cm;
Electrical parameters:
Working current:
Less than 90mA at 5V (less than 5mA when the relay is not operating)
Less than 50mA at 12V (less than 5mA when the relay is not operating
Less than 30mA at 24V (less than 5mA when the relay is not operating)
load capacity:
Maximum load capacity of the relay normally open port: DC 0-30V/10A, AC 0-250V/10A
Maximum load capacity of relay normally closed port: DC 0-28V/10A, AC 0-125V/10A
Working temperature: recommended -20℃—60℃ (limit working temperature range -30℃—70℃)

Instructions for use:
1. The photoresistor module is sensitive to ambient light and is generally used to detect changes in the brightness of the ambient light;
2. When the ambient light of the module is darker than the set threshold, the relay is closed, and the common end is connected to the normally open end (disconnected from the normally closed end). When the ambient light is brighter than the set threshold, the relay is turned off, and the common end Disconnect with the normally open terminal (connect with the normally closed terminal);
3. The three ports of common, normally open, and normally closed are equivalent to a dual-control switch. When the relay coil is energized, the common end and the normally open end are connected; when there is no power, the common end and the normally closed end are connected;
