5V 12V low level trigger One 1 Channel Relay Module interface Board Shield For PIC AVR DSP ARM MCU for Arduino
Product description:
1, The module complies with international safety standards, control area load area isolation groove;
2, Genuine relay ;
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
