Supply voltage: 12VDC ; Current:> 100mA ; Load: 250V 10A AC or 30V 10A DC.
12 V power input is designed for relay board regulator transistor to provide sensor Used to make the product more stable and reliable.
Onboard optocoupler isolation drive relay, the effective protection of the chip to make the product more reliable work.
Distribution bit sensitivity adjustment, start relay threshold set by adjusting potentiometer, when the dark this threshold, the module relay is energized, bright this threshold, the relay release.
Light detection and brightness detection, detection can be adjusted via potentiometer brightness valve point comes relays, and do all kinds of brightness detection switch, you can control all kinds of street lights automatically turn on at night, during the day and automatically turns off and car supplies control and automation equipment.
