Description
4CH Relay Module
Robust design using an NPN transistor to drive each relay with a PC817 optocoupler.
Relay on LED indicator for each of the four relays.
A diode is provided for reverse polarity protection.
2 pin PBT provides easy connection of the power supply to the PCB.
The 7-pin connector provides easy connection of the PCB to the drive interface.
Supply voltage 5V DC
