1 channel 5V Relay Module with Optocoupler
Complying with international safety standards, this 1 channel 5V relay Module with optocoupler modules for isolation in both the control and load areas. It is equipped with a single genuine relay.
The 1 Channel 5V 10A Relay Module with Optocoupler inputs are isolated to safeguard against damage to sensitive control circuitry.
The power supply and relay instructions are switched off, while the disconnect is also lit. The input signal, along with the common Terminal, starts conducting. This module can act as a single chip for controlling appliances and works with both DC and AC signals, making it suitable for controlling 220V AC loads.
Various microcontrollers, including Arduino, AVR, PIC, ARM, and others have the capability to control it.

In both the high and low level-triggered modes, friends who are unfamiliar, take a look.
High-level trigger is essentially a way of activating a signal input by short-circuiting the cathode with VCC. In simpler terms, it involves detecting the signal voltage between the input and trigger.
The term “low-level trigger” describes the voltage between the input terminal and Earth OV trigger, which can be seen as a short circuit between the signal input terminal and GND negative electrode. This is one method of connecting a 1-channel relay module.
