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.
- 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
