4 Channel 5V 10A Relay Module

• 4 channel relay module 
• TTL level control signal
• Number of I/O Channels: 1
• Indication LED for relays status

The 10A 4 Channel Relay Module is a 4 channel relay module that can be used to control the lighting, electrical and other equipment. The modular design makes it easy to expand with the Arduino board or other MCU board PIC, ARM and MSP430. It shows the relay output state with a light-emitting diode.
