KSh 1,000.00

8-channel 5V optocoupler-isolated relay module for home automation and control panels.

In stock

This 8-channel 5V relay module with optocouplers lets one microcontroller switch eight separate AC or DC loads. Each channel is isolated by an optocoupler, which protects your Arduino, ESP32 or Raspberry Pi from the load side.

Key features

  • 8 independent relays, each with COM, NO and NC contacts
  • Optocoupler isolation on every channel
  • LED indicator for each relay

Specifications

Channels 8
Coil voltage 5V DC
Contact rating 10A 250V AC / 10A 30V DC (typical)

Typical uses

  • Home and building automation
  • Multi-zone irrigation
  • Control panels and PLC projects

Tip: With all eight relays on, the module draws several hundred mA. Power the relays from a separate 5V supply, not the microcontroller.
