5V 2-Channel Solid State Relay (SSR)

Wiring Connections:

• Control Side:
  • VCC: Connect to the 5V DC power supply.
  • GND: Connect to the ground of the 5V DC power supply.
  • IN1: Connect to the digital output pin of your control device (e.g., Arduino) to control Channel 1.
  • IN2: Connect to the digital output pin of your control device to control Channel 2.
• Load Side:
  • L1 (Load 1): Connect to one terminal of the load for Channel 1.
  • L1 (Load 1): Connect to the load power source.
  • L2 (Load 2): Connect to one terminal of the load for Channel 2.
  • L2 (Load 2): Connect to the load power source.

Power:

• Input Voltage (Control Side): 5V DC
• Power Consumption: Low,  a few milliwatts when active
• Load Voltage: Up to 240V AC
• Load Current: Maximum 2A per channel

Input and Output:

• Input:
  • Control Signals: Digital signals from a microcontroller or control system (high or low) to activate/deactivate the relays.
• Output:
  • Load Switching: Provides switching capability for AC loads up to 240V and 2A per channel.

Physical Characteristics:

• Dimensions: Compact design,  around 50mm x 40mm x 25mm
• Weight: Light, approximately 30 grams
• Mounting: Usually includes mounting holes or options for DIN rail mounting
• Construction: Durable plastic housing with exposed terminals for connections

Technical Specifications:

• Control Voltage: 5V DC
• Load Voltage Range: 24V AC to 240V AC
• Load Current Capacity: 2A per channel
• Isolation Voltage:  2500V AC between control and load sides
• Switching Speed: Fast, with negligible delay compared to mechanical relays

Additional Features:

• LED Indicators: Each channel has an LED to show the relay’s status (on or off).
• Heat Dissipation: Designed to handle the heat generated during operation,  includes a heat sink or cooling fins.
• Durability: Solid-state design ensures longevity and reliability even in harsh environments.

How to Use:

• Connect Power:
  • Attach VCC: Connect the VCC pin to a 5V DC power source.
  • Attach GND: Connect the GND pin to the ground of the 5V DC power supply.
• Connect Control Signals:
  • IN1 and IN2: Connect these pins to the digital output pins of your control device (e.g., microcontroller, Arduino) to control the relays. When a HIGH signal is sent to these pins, the corresponding relay channel is activated.
• Connect Load:
  • Load Connections: Connect the load terminals to the load side (L1 and L2) and the AC power source. Ensure proper safety measures are in place while working with high voltages.
• Programming:
  • Write Code: Program your control device to send HIGH or LOW signals to IN1 and IN2 based on your application needs.
• Testing:
  • Verify Connections: Check all connections to ensure they are secure and correctly wired.
  • Test Operation: Send control signals to the relay and verify that the connected loads are switched on and off as expected.
• Integration:
  • Use in Projects: Incorporate the SSR into your projects to control high-voltage AC devices with low-voltage DC signals. Suitable for applications in home automation, industrial control, and other electronic systems requiring safe and reliable switching.

The 5V 2-Channel Solid State Relay is an essential component for controlling AC loads with DC signals. Its solid-state technology, reliability, and ease of use make it suitable for various applications where traditional mechanical relays might not be ideal.
