3-Channel Relay Module – 5V Relay Board for Arduino, Raspberry Pi

Description The 5V 3-Channel Relay Board is a reliable solution to control up to 3 AC or DC high-voltage devices using low-voltage microcontrollers like Arduino, ESP32, or Raspberry Pi. Each relay operates independently with opto-isolation for protection and jumper-controlled trigger logic. Best suited for automation projects, IoT systems, smart switches, and load control, this board offers easy wiring, LED indication, and safe operation with high-power devices. Features: 3 relays with opto-isolation (SPDT type) Trigger mode: HIGH or LOW selectable (jumper) Status indicator LEDs for each channel Compatible with 3.3V & 5V logic systems Screw terminals for secure AC/DC load connection Compact board with mounting holes Long-life relay switches rated for 10A loads Specifications: Voltage: 5V DC (VCC) Input Signal: 3.3V–5V logic Relay Contact Rating: 10A @ 250V AC or 10A @ 30V DC Interface: IN1, IN2, IN3, VCC, GND Relay Type: SPDT PCB Size: ~68mm x 50mm Indicators: Power LED 3 Relay Status LEDs Isolation: Opto-coupler based Package Includes: 1 x Adiy 5V 3-Channel Relay Module
