12V 16-Channel Optocoupler Relay Board Module LM2576 Power Supply

The 16-Channel 12V Relay Module Board with Power LM2576/Optocoupler Protection is designed for easy control of various appliances and equipment. Each relay is capable of handling 230 volts at 10 Amps or 30 volts DC at 10 Amps. The module features isolated trigger pins using optocouplers, ensuring safety for your circuit. It includes 16 LED indicators to display the status of each relay. The module can be controlled directly by a wide range of microcontrollers, making it versatile for different applications.

  Features:  

• 12V relay with AC contact capacity of 10A 250V and optocoupler protection.
• The onboard power supply module eliminates the need for an external power supply.
• The I/O port driver is active and low.
• Can be used as a microcontroller development board module and for appliance control, PLC extended output.
• Uses top-quality isolation optocouplers for strong anti-jamming ability and stable performance.
• Each relay's common terminal "COM" is independent, allowing easy access to different signals.
• Each relay has normally closed and normally open ports.
• Equipped with motion lights for each relay.
• All interfaces can be directly connected through terminal leads.
