Product description: 1-channel relay module - contact of 3A/250 VAC. AC / 30V DC coil 5V
The module allows to control the actuators consuming the currentup to 3 Athrough the port of the microcontroller or any development kit (includingArduino,Rasbperry PiandSTM32Discovery). RelayHK4100Fwith a coil powered with the voltage of 5 V.
The connection of the relay module
For proper operation, it is sufficient to connect the power of the relay coil and the digital control signal. Pins are the standard goldpin straps with the pitch of 2.54 mm, which enable the connection using the popular connecting cables.
The relay has the following pins
- VCC- power of the optocoupler
- DAT- control input of the relay, activated by the high status
- GND- ground of the system, all the GND pins are connected together
- connectors KF (ARK)- relay contacts
Examples of the application of the relay
- Driver of lighting
- The driver of the executive systems
- Switch for electric devices, includingthe motors
