RELAY-2CH-5VDC, 2-Channel Relay Module, PCB Mount

The RELAY-2CH-5VDC is a compact, versatile 2-channel module based on the Songle SRD-05VDC-SL-C relay. It allows 5V control systems to operate high-power AC or DC devices through opto-isolated triggering, making it ideal for automation, home control, and DIY projects. The board includes screw terminals for easy wiring and onboard indicators to visualize relay activity.

Key Features:

• 5V Logic Compatible: Easily interfaces with Arduino, Raspberry Pi, ESP8266, and other 5V systems
• Dual Independent Channels: Control 2 AC/DC loads separately
• High Power Switching: Supports 10A at 250VAC or 30VDC per channel
• SPDT Relay Outputs: Each channel has Normally Open (NO), Normally Closed (NC), and Common (COM) terminals
• Opto-Isolated Input: Provides safe signal isolation between control and load sides
• Status LEDs: Onboard indicators for each relay channel simplify debugging and monitoring

Additional Specifications:

• Type: Electromechanical Relay Module
• Number of Channels: 2
• Coil Voltage: 5Vdc
• Switching Voltage (VDC)/Current: 30Vdc At 10A
• Switching Voltage (VAC)/Current: 250Vac At 10A,125Vac At 10A
