1CH 5V RELAY MODULE WITH OCTO

The 1-Channel 5V Relay Module with Optocoupler provides a single isolated relay output for controlling high-voltage AC or DC loads from a microcontroller. Optocoupler isolation protects sensitive control circuitry from load-side interference. Supports both high-level and low-level trigger modes.

Compatible with Arduino, AVR, PIC, ARM, and any 5V TTL logic microcontroller. Suitable for switching 220V AC appliances, motors, and DC loads.

Features:

• 1 relay channel with optocoupler isolation
• Operating voltage: 5V DC
• Switching capacity: 10A @ 250V AC / 10A @ 30V DC
• Supports high-level and low-level trigger modes
• Power supply indicator LED
• Relay status indicator LED
• 1 x NC and 1 x NO contact per relay
• 4 mounting holes (3.1mm diameter)
• Compatible with Arduino, AVR, PIC, ARM, MSP430
