2 Channel 12V Relay Module with Optocoupler

The 12V Dual Channel Relay Module is designed with safety in mind, featuring isolation grooves between control and load areas and an optical coupling isolation module. This ensures reliable and stable triggering of the relays. The module uses a double FR-4 circuit board design with a high-end SMT process, providing high reliability.

  Features:  

• Equipped with high-current relays (10A @ 250VAC / 10A @ 30VDC)
• Can control both AC and DC appliances such as solenoids, motors, lights, and fans
• High-quality screw terminals (Terminal Block) for quick and easy connection
• Includes a freewheeling diode to protect your microcontroller
• Input Signal Pin connected to Burg stick for easy accessibility
• LED status indicators to indicate relay ON/OFF status
• Mounting holes for easy installation
• Signal input with high-level signal, the common and often start conduction
• One normally opened and normally closed contact for each relay
• Blue KF301 terminal line for convenience

  Specifications:  

• Channel: 2
• Operating Voltage (VDC): 12
• Current Capacity at AC250V: 10A
• Current Capacity at DC30V: 10A
• Dimensions: 50mm x 40mm x 20mm
• Weight: 30g

  Module Interface:  

• Positive (VCC): Connect the power supply
• GND: Connect power negative
• IN1: Relay module (effective) high-level trigger signal trigger end
• IN2: Relay module (effective) high-level trigger signal trigger end

  Meaning of High Level and Low Level:  

• High-level trigger: Uses the anode voltage at the VCC connection for triggering
• Low-level trigger: Uses the negative voltage at the GND connection for triggering

  Package Includes:  

• 1 x 2-Channel Relay Module (with light coupling) 12V
