4 Channel 30V Relay Shield Module

• Arduino/Maduino Shield compatible
• Relay screw terminals
• Working status indicators for each relay
• Operating voltage: 4.75V~5.25V

The 4 Channel 30V Relay Shield Module is based on four high quality relay that can control up to 30VDC or 250VAC loads to Maduino or Arduino boards. It provides NO (Normally Open) / NC (Normally Closed) interface. It could be a nice solution for controlling devices that could not be directly controlled by Arduino's Digital I/O ports.
