5V 2 Channel Relay Module for Arduino

• The active low relay board features 5V relays that can be switched on and off via an opto-isolated digital input, ensuring electrical isolation between the control circuit and the relay mechanism. To activate the relays, connect a microcontroller to the output pin, which requires a minimum input voltage of 1V to turn the relays ON.

• These relay boards are versatile and support both 5V and 3.3V devices, making them suitable for a variety of applications, including Raspberry Pi, Arduino, and PIC microcontrollers. Their compatibility and ease of integration make them an excellent choice for numerous electronic projects and automation tasks.

Features:

• 2 Channels
• Maximum switching voltage: 250VAC / 30VDC

• Each relay features an LED indicator.
• Dimensions: 51 x 39 x 18mm (Length x Width x Height)
• GND - Connect 0V to this pin.
• IN1 - Controls relay 1, active Low Relay will turn on when this input goes below about 2.0V
• IN2 - Controls relay 2, active Low Relay will turn on when this input goes below about 2.0V
• VCC - Connect 5V to this pin. Is used to power the optocouplers
