The 5V 4-Channel Relay Module Optical Isolated switches four 10A circuits for electronic systems. It operates at 5V input voltage. The module uses electromagnetic relays for load control. It connects via a four-pin interface (VCC, GND, IN1-IN4). VCC supplies power, GND provides grounding, and IN1-IN4 receive low-level signals. A microcontroller sends 15-20mA pulses to each IN pin to activate relays. Opto-isolators separate control inputs from relay outputs for safety. The module switches 250VAC or 30VDC loads with 70mA draw per relay. It measures 50mm x 75mm. It functions from -40°C to 85°C. This module integrates with Arduino systems.
