5 V-os alacsony trigger egy 1 csatornás relé modul interfész kártya árnyékolás PIC AVR DSP ARM MCU
5V low level trigger One 1 Channel Relay Module interface Board Shield PIC AVR DSP ARM MCU
Product description:
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
