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
- 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 connector provides easy connection of power source to the PCB
- On Board Voltage Regulator U1 (7805) provides +5 VDC supply to ongoing interface circuit connected to this board
- A 10 pin Header connector provides easy connect of this PCB to the driving interface
