5V low level trigger One 1 Channel Relay Module interface Board Shield PIC AVR DSP ARM MCU

1, the module complies with international safety standards, the load control area and regional isolation tank;

2, using loose music authentic relay;

3, with the power and relay instructions, pull off, disconnect does not shine;

4, when the input signal is a signal, often beginning with a common terminal will be turned on;

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

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

7, there is a normally open and one normally closed contact;

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

About the high and low trigger description.if you don’t understand .pls check below

Means there is a high trigger voltage trigger, can be understood as a way to signal input terminal and VCC between the positive short trigger signal input and ground;

Refers to a low voltage trigger signal input terminal and ground for OV trigger mode, can be understood as a way to signal input terminal and GND short circuit triggered the negative
