8-channel relay module 5V with optocoupler isolation for switching loads

A multi-channel relay module with 8 channels and a 5V power supply is designed for switching power electrical circuits using signals from microcontrollers. Each channel on the board is equipped with an electromechanical relay and a separate optocoupler, which provides galvanic isolation between the control logic and the power section, protecting equipment from interference and voltage surges. The module can switch devices with voltages up to 250V AC or 30V DC at currents up to 10A. The board features convenient screw terminals and a JD-VCC jumper for flexible power configuration. Features: Product type: multi-channel power relay module / relay board with optocouplers (8-Channel Relay Module) Specifications: 8 independent channels, 5V DC control voltage, switching load up to 10A (250V AC / 30V DC), built-in optocoupler isolation for each channel, terminal blocks, JD-VCC jumper Purpose: safe control of powerful household and industrial appliances using microcontrollers and logic boards in automation and smart home systems
