1 channel 5V 10A Relay Control Board Module with Optocoupler
This module is a 1-channel 5V 10A relay control board featuring optocoupler modules. It adheres to international safety standards with isolation trenches separating the control and load areas. It incorporates a genuine single relay.
The inputs of the 1-Channel 5V 10A Relay Module are isolated to safeguard any delicate control circuitry.
The module includes indicators for power supply and relay status. The power indicator lights up when the module is powered. Upon receiving an input signal, the relay activates, connecting the common terminal to the signal terminal. This module can control appliances using a single chip and is compatible with both DC and AC signals, handling up to a 220V AC load.
It is controllable by a broad spectrum of microcontrollers, including Arduino, AVR, PIC, ARM, and others.
Note: Regarding high-level and low-level-triggered modes, for those unfamiliar, please note:
A high-level trigger means the signal voltage between the input and the trigger is present, which can be seen as the signal input being triggered by a short circuit with the VCC cathode.
A low-level trigger means the signal voltage between the input terminal and Earth OV is present, which can be seen as the signal input being triggered by a short circuit with the GND negative electrode, facilitating the 1-channel relay module connection.
