Description

This 1 channel 5V 10A relay control board module with optocoupler modules is compliant with international safety standards, control and load areas isolation trenches it has a single relay a genuine.
The inputs of 5V 1-Channel Relay 10A Relay Module are isolated to protect any delicate control circuitry.
The power supply and relay instructions, lit, a disconnect are off. The input signal, signal, common Terminal and start conducting. It can be used as a single chip module for appliance control and work with both DC or AC signals where you can control the 220V AC load.
A?wide range of microcontrollers such as?Arduino, AVR,?PIC,?ARM and so on can control 1 channel 5V 10A Relay Control Board Module with Optocoupler.
Note: On the high level and low level-triggered mode, friends who do not understand, have a look

High-level trigger refers to the signal voltage between input and trigger, can be understood as a signal input with VCC cathode short-circuit triggered a way;
Low-level trigger refers to the signal voltage between the input terminal and Earth OV trigger, can be understood as a signal input terminal and the GND negative electrode short circuit triggered is?a way? 1-channel relay module connection.
