Key Features

• Safety Compliant Design:
  Features an isolation groove that separates the control circuit from the load area, enhancing operational safety.

• Optical Coupler Isolation:
  Integrated opto-isolator provides stable and reliable triggering, minimizing electrical noise and interference.

• High-Quality PCB Construction:
  Manufactured using a double-layer FR-4 PCB with SMT components for improved durability and performance.

• Indicator LEDs:
  Equipped with clear LED indicators to display power status and relay operation.

• Logic-Level Triggered:
  Activated via high-level input signal; supports both normally open (NO) and normally closed (NC) contacts.

• User-Friendly Terminal Block:
  Includes a blue KF301 screw terminal for convenient wiring and secure connections.

Applications

• Home automation systems

• Microcontroller interfacing (Arduino, Raspberry Pi, ESP8266, etc.)

• Appliance control

• Smart energy systems

• Industrial automation projects

Note:

• Ensure the control signal provided is a high-level logic signal (typically 5V) to activate the relay.

• Do not exceed the relay's rated voltage or current to maintain operational safety and longevity.

• The opto-isolated design ensures protection for the control circuit when switching higher voltages.
