PRODUCT NAME
4-Channel Relay Module – 5V

DESCRIPTION
The 4-Channel Relay Module (5V) is a versatile electronic component that allows low-voltage devices, such as microcontrollers, to safely control high-voltage or high-current loads. It contains four independent relays, each capable of switching AC or DC devices, making it ideal for home automation, robotics, industrial projects, and IoT applications. The module operates at 5V DC and can interface directly with development boards like Arduino or, with level shifting, Raspberry Pi. Its design ensures safe and reliable switching while protecting low-voltage circuits from electrical surges.

KEY FEATURES
The module features four separate relays, each controlled via TTL logic signals, allowing precise management of multiple devices. It typically supports 10A at 250VAC or 10A at 30VDC, making it suitable for various appliances and motors. Optocoupler isolation on each channel (model dependent) provides added safety by separating the control circuit from the high-voltage load. LED indicators for each relay channel offer visual feedback, and screw terminals provide secure connections for easy installation in DIY or professional setups.

PACKAGE INCLUDES
The package includes one 4-Channel Relay Module (5V), ready to connect to your control circuits and devices.

APPLICATIONS
This relay module is ideal for controlling home automation systems, industrial and DIY automation projects, robotics, and other electronics that require switching of AC or DC devices. It can be used in IoT projects to remotely control lights, motors, fans, or other appliances, making it a practical tool for learning and implementing automation safely.
