Relay module 1 channel - 3A/250VAC contacts - 5V coil

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.

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

• Driver of lighting
• The driver of the executive systems
• Switch for electric devices, includingthe motors

• The VCC supply voltage: 5 V
• Activated by the high status
• Relay: HK4100F-DC5V-SHG (documentation)
  • Coil voltage: 5 V
  • The maximum voltage of contacts: 250 VAC, 30 VDC
  • Maximum current: 3 A
• Board sizes: 41 x 26 x 15 mm
• Diameter of mounting holes: 3 mm
