8 CHANNEL RELAY BOARD WITH ON BOARD 5V REGULATOR FOR EASY MICRO-CONTROLLER INTERFACE

8 Relay Board for IR/RF Interface project offers 8 relay output control for your

• Eight 12V Single Pole Double Throw (SPDT) relays
• Transistor driven control with LED indication
• Diode protection for Back EMF generated
• 3 Pin Screw terminal connector for easy connections of all relay contact pins
• Screw terminal connector for easy connection of the input power supply
• Onboard 5V @ 1A regulator IC to source supply to connecting interfaces
• 10-Pin well marked header connector for ease of connection
• Power-On LED indicator
• PCB dimensions 101 mm x 110 mm

 

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 and otherwise.

 

Some of the features of this relay board are

1. Robust Design using NPN transistor to drive each relay
2. Relay On Indicator LED for each of the eight relays
3. Back EMF / Surge protection diode across each relay to protect driving circuit
4. 3 Pin PBT connector for connecting load to the relay
5. Reverse polarity protection diode (D17) provided
6. 2 pin PBT connector provides easy connection of power source to the PCB
7. On Board Voltage Regulator U1 (7805) provides +5 VDC supply to ongoing interface circuit connected to this board
8. A 10 pin Header connector provides easy connect of this PCB to the driving interface
