4 channel relay module
Do you want to intelligently control your car or home electrical appliances using an Arduino or other microcontroller? With this relay module you will be able to do this. The module uses high-quality electrical components, so it can control high-current and high-voltage car or home electrical appliances.
Technical data and features:
- 4-channel relay module with logic signal control
- Logic signal voltage: 5V DC, suitable for Arduino and other similar microcontrollers
- Relay controlled current: up to 250V 30A AC, or 30V 30A DC
- The LED indicates the operating status of the relay and the board
- Normally open and normally closed lines (NC normally closed, NO normally open)
- Common ground for signal connection
- The control board is specially insulated from the noise caused by the alternating current flowing through the relays.
- Screw connections ensure strong contact
- Relay testing buttons
