5V 8 Channel Relay Board

5V 8 Channel Relay Module for any microcontroller TTL interface with 7A load capacity for switching AC or DC

• Can be used as microcontroller development board module can be used as home appliance control
• 5V to TTL control signal
• With the The DC control signal, 220V AC load can be controlled.
• here is a normally open and one normally closed contacts with 3 terminal screw blocks for easy interface.
• power indication LED
• A control indicator
• Transistor driven
• The control pin has a pull-down circuit to prevent malfunction of the relays.
