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 label:yes
