8 Channel Relay Board with onboard 5V regulator

This is a general purpose relay board accepting 8 inputs to drive 8 relays providing control requirement in your project. This board can also be used as an add-on card for the various Development board that we provide.

Features

• Robust Design using NPN transistor to drive each relay
• Relay On Indicator LED for each of the eight relays.
• Back EMF / Surge protection diode across each relay to protect driving circuit.
• 3 Pin PBT connector for connecting load to the relay.
• Reverse Polarity protection diode (D17) provided.
• 2 pin PBT provides easy connection of power source to the PCB.
• On Board Voltage Regulator U1 (7805) provides +5V DC supply to ongoing interface circuit connected to this board.
• A 10 pin Relimate Connector provides easy connect of this PCB to the driving interface.
• Supply voltage 12 ~ 15 V DC
