Multi Channel Optocoupler Relay Module

You might wish to utilize your Arduino to operate a high-voltage device, such as a lamp, fan, or other household appliance, in your next project. However, because the Arduino operates on 5 volts, it cannot control this high-voltage equipment directly. Multi Channel Optocoupler Relay Module comes into play in this situation. This self-contained module is cheap, easy to connect, and suitable for homebrew projects that require switching small quantities of AC or DC power.

Key Product Features:

• A specialized two-way driver IC is used in the dual trigger design.
• To protect it from interference, use a diode with a constant current.
• The relay contact component uses a double-cloth line for high current, making it safe and dependable.
• The input and output are 5.08mm wiring connections, making wiring easier and more suitable for PLC control.
• The input terminals’ high and low levels can be freely set, and the control mode is more versatile.
