Product description:

1,The module complies with international safety standards,control area load area isolation groove;

2,Genuine relay Songle;

3,With the power and relay action instructions,pull bright disconnect does not shine;

4,When a signal in the signal input terminal,the common terminal and the normally start conduction;

5,Microcontroller development board can be used as a module that can be used as a home appliance control;

6,The control of the DC or AC signal,can control 220V AC load;

7,There is a normally open and a normally closed contact;

8,Blue KF301 terminals to the line of control is more convenient.

Description of the high and low trigger,friends do not understand Take a look at:

High level trigger is a trigger voltage between the signal input and ground can be understood as a way of the signal input terminal and VCC cathode short trigger;

Low trigger means is the voltage between the signal input terminal and the ground for the OV trigger mode can be understood as a way of the signal input terminal and GND negative short trigger
