Product Description
This module is a 1-channel 5V 10A relay control board with optocoupler modules. It meets international safety standards and has isolation trenches between the control and load areas. It uses a genuine single relay.
The inputs of the 1-Channel 5V 10A Relay Module are isolated to protect any sensitive control circuitry.
The module has indicators for power supply and relay status. When the power is on, the indicator is lit. When the input signal is received, the relay is activated and the common terminal is connected to the signal terminal. The module can be used to control appliances with a single chip and can work with both DC or AC signals. It can handle a 220V AC load.
A wide range of microcontrollers such as Arduino, AVR, PIC, ARM and so on can control it.
Note:Â 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.
