16 Channel Relay Module 12V with Light Coupling LM2576

12V 16-Channel Relay interface board, Be able to control various appliances, and other equipments with large current. It can be controlled directly by Micro-controller (Arduino , 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic) .

12V 16-Channel Relay interface board, and each one needs 15-20mA Driver Current

Features

• 12V relay with AC contact capacity of 10A 250V and optocoupler protection.
  
• The onboard power supply module does not need an external power supply. I / O port driver is active low.
  
• The module can be used as a microcontroller development board module and also as appliance control, PLC extended output.
  
• It is using the industry’s top-quality isolation optocouplers, strong anti-jamming ability, stable performance.
  
• Each relay common terminal “COM” are independent, user-friendly access to different signals, each relay are normally closed and normally open with the port.
