A 5V 4 Channel Relay Module Without Optocoupler is an electronic device designed to control high-voltage appliances or devices using low-voltage signals. This module operates on a 5-volt power supply, making it compatible with microcontrollers, development boards, and other low-voltage control systems.
This is a 4-channel 5V 10A isolated relay module, each relay can be switched individually via isolated optical digital inputs. The standard interface can be directly connected to the microcontroller, and it is now controlled by various microcontrollers, such as Arduino, AVR, PIC, ARM, DSP, etc., which is very convenient.
5V 4 Channel Relay Module provides four independent relay channels, allowing you to control up to four separate high-voltage devices or circuits. It is equipped with a screw terminal block, with mounting bolt holes (diameter: 3.1mm) on both sides and is easy to install.
Unlike traditional relay modules, this version does not include optocouplers for isolation. 5V 4 Channel Relay Module can simplify the circuit design but may require additional precautions for high-voltage applications. Each relay channel typically has a specified switching capacity, indicating the maximum voltage and current it can handle. Common configurations include options for both AC and DC loads.
Each relay channel typically provides both a normally open and normally closed contact, allowing for versatile control options. 5V 4 Channel Relay Module requires a low-voltage trigger input (usually around 3.3V or 5V) to activate the relay and switch the connected load. The relay modules include LED indicators for each channel, providing visual feedback when the relay is activated.
The 5V 4-Channel Relay Module provides a versatile solution for controlling high-powered devices. Whether you’re automating home appliances or industrial machinery, this module ensures reliable operation without the need for an optocoupler. With its robust build and advanced circuitry, this relay module guarantees safe and efficient performance. It features high-quality relays that can handle substantial loads, making it suitable for a wide range of applications.
These facilitate easy and secure connections to the external power supply, control signals, and the load. Since 5V 4 Channel Relay Module module lacks optocouplers for electrical isolation, users need to take additional precautions to ensure safety, especially when dealing with high-voltage applications.
Advanced users may modify or hack 5V 4 Channel Relay Module for specific applications, such as creating custom timing circuits or adding additional safety features. It can be used with various microcontrollers and development platforms like Arduino, Raspberry Pi, ESP8266, and others.
Common applications for 5V 4 Channel Relay Module include home automation, robotics, industrial control systems, IoT devices, and any project where high-voltage loads need to be controlled.
Caution: When working with high-voltage circuits, it’s important to follow safety precautions and ensure proper insulation and isolation methods to avoid electrical hazards.
