5V 16 Channel Optocoupler Relay Module LM2576 Power Supply

The 16-Channel 5V Relay Board Module with Optocoupler is a versatile module suitable for various applications. It features 16 relays with a high current capacity and optocoupler protection, making it ideal for use with microcontrollers like Arduino, 8051, AVR, PIC, PLC, DSP, ARM, MSP430, and TTL logic circuits.

  Features:  

• 5V relay with AC contact capacity of 10A at 250V and optocoupler protection.
• The onboard power supply module eliminates the need for an external power supply, with an active low I/O port driver.
• Strong anti-jamming ability and stable performance due to high-quality isolation optocouplers.
• Each relay's common terminal (COM) is independent, allowing user-friendly access to different signals, with both normally closed and normally open ports available.
• Equipped with motion lights for each relay.
• All interfaces can be directly connected through terminal leads for convenience.
