5V Relay Module 1 Channel Low level for SCM Household Appliance Control For Arduino

1 channel 5V 10A with optocoupler low level trigger Relay Module 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
