This is a 12V 16 Channel Relay Module with a Light Coupling LM2596 Power Supply that can control a wide range of appliances and other high-current devices. Microcontrollers (Arduino, 8051, AVR, PIC, DSP, ARM, MSP430, TTL logic) can be used to control it directly. This is a 12V 16-Channel Relay Interface Board with 15-20mA Driver Current for each individual relay. The board has a status indicator LED for each relay output. 


  • Number of Channels: 16
  • Control Signal voltage: 5V, active low
  • Load Voltage: AC 250V/10A, AC 125V/15A DC 30V 10A
  • Input Voltage: 12V DC
  • Each board needs 15-20mA Driver Current
  • I/O port driver is active at low level.
  • 1-16 channels optionally fully open/closed, or any channel.
  • Standard interface that can be controlled directly by the microcontroller.
  • Indication LEDs for Relay output status.
  • Independent common end COM makes the relay convenient for users to access different signals.
  • Use optocoupler protection with high safety performance
  • Widely used for all MCU control, industrial sector, PLC control, smart home control
