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:

1. 3 relays with opto-isolation (SPDT type)

2. Trigger mode: HIGH or LOW selectable (jumper)

3. Status indicator LEDs for each channel

4. Compatible with 3.3V & 5V logic systems

5. Screw terminals for secure AC/DC load connection

6. Compact board with mounting holes

7. Long-life relay switches rated for 10A loads
