8CH 5V RELAY MODULE

The 8-Channel 5V Opto-Isolated Relay Module allows microcontrollers to independently control 8 high-current or high-voltage loads. Each relay is isolated via optocoupler for safe separation of control and load circuits. Supports both high-level and low-level trigger modes, making it compatible with 3.3V, 5V, and 12V microcontroller outputs.

Suitable for Arduino, AVR, PIC, ARM, Raspberry Pi, PLC, and any TTL-logic controller. Applications include smart home control, industrial switching, appliance automation, and AC/DC load switching.

Features:

• 8 independent opto-isolated relay channels
• Trigger voltage: 5V DC (active low or active high selectable)
• Switching capacity: 10A @ 250V AC / 10A @ 30V DC
• Supports high-level and low-level trigger modes
• Power indicator LED + relay status LED per channel
• Each relay: 1 x COM, 1 x NO, 1 x NC terminal
• Compliant with international safety isolation standards
• Compatible with Arduino, Raspberry Pi, PLC, ARM, AVR, PIC
