2-Channel 5V Relay Module with Optocoupler

2-Channel 5V Optocoupler Isolated Relay Module Board

The 2-Channel 5V Relay Module enables microcontrollers to independently switch two separate electrical circuits. Optical isolation protects sensitive microcontroller pins from high-voltage spikes and electrical noise.

Key Features & Specifications:

• Channels: 2 Independent SPDT Relays
• Coil Voltage: 5V DC
• Switching Rating: AC 250V/10A, DC 30V/10A per channel
• Optical Isolation: High-speed optocouplers ensure complete galvanic isolation
• LED Indicators: Individual channel status LEDs for visual feedback
• Output Connectors: Screw terminals for NO, COM, and NC contacts

Applications:

• Dual-load home automation systems (e.g. Light + Fan control)
• Motor forward/reverse direction switching
• Smart power sockets and agricultural automation
