Automatic Control Module DC12V Photorelay Light Photosensitive Resistor XH-M131 Brightness Switch Module

automatic control module 5V 12V 24V photorelay light photosensitive resistor XH-M131 brightness switch module

Working voltage: 5V, 12V, 24V (please choose what you need)

This module can be used for light detection, brightness detection, with power indicator light (red) and relay indicator (blue), and with fourM3The screw mounting holes, which is convenient to install, can bring the board relay through the potentiometer adjusting sensitivity, and can be a variety of brightness detection control switch, can be used in such lights, night automatically open, daytime automatically extinguished, and other automation equipment.

Board parameters

1Module use12VThe power supply has anti reverse connection function, and the reverse power supply can not damage the module;

2Normally open interface maximum load capacity: AC0V--125V/20ADC, DC0V--14V/20A;The module output has three ports on the port sideCOM(normally open)CK(normally closed)CBThe three port is equivalent to a double control switch, when the relay coil is provided with an electric current, the common end is connected with the normally open conducting, and the common end is connected with the normally closed end;COMEnd generally through the load connected to the power source, often beginning to connect the power supply;

3And the sensitivity can be adjusted through the potentiometer, by adjusting the potentiometer, set the starting relay threshold, when the light is dark on the threshold, relay module, light on the threshold, the relay is switched off;
