2. Use Relay;

3. It Has the Action Indication of Power Supply and Relay, Which Is on and off;

4. When There Is a Signal at the Signal Input Terminal, the Public Terminal Will Conduct with the Normal Beginning;

5, Can Be Used as Single Chip Microcomputer Development Board Module, Can Be Used as Home Appliance Control;

6, Control DC Or AC Signal, Can Control 220V AC Load;

7. There Is One Normally Open and One Normal Closed Contact;

8. It Is More Convenient to Connect the Blue Kf301 Terminal to the Control Line.

for the Description of High-Level and Low-Level Triggering Methods, Please Have a Look If You Don't Understand:

High Level Trigger Refers to the Trigger Mode with Voltage between Signal Input Terminal and Ground, Which Can Be Understood as a Way of Short Circuit Trigger between Signal Input Terminal and VCC Positive Pole;

Low-Level Trigger Refers to the Trigger Mode in Which the Voltage between the Signal Input Terminal and the Ground Is OV, Which Can Be Understood as a Way to Trigger the Short Circuit between the Signal Input Terminal and GND Negative Pole.

3, with power and relay action instructions, the light is closed, the light is off;

4. When there is a signal at the signal input end, the common end and the normally open end will be turned on;

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

6, control DC or AC signal, you can control 220V AC load;

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

8. The blue KF301 terminal is more convenient to connect to the control line.

For the description of the high-level and low-level trigger modes, please don't understand the friends:

  The high level trigger refers to the trigger mode of the voltage between the signal input terminal and the ground, which can be understood as a way to trigger the short circuit of the signal input terminal and the VCC positive terminal;

  Low-level triggering refers to the triggering mode of the voltage between the signal input terminal and ground is OV, which can be understood as a way to trigger the short circuit of the signal input terminal and the GND negative terminal.
