Relay Module 6 Channel 5V

The module has six relays with a coil powered with a voltage of 5 V along with optoelectronic insulation. The system allows you to control actuators with microcontroller ports or any development kit.

Specifications:

• Supply voltage VCC: 5 V
• Activated with the low-status
• Relay
  • Coil voltage: 5 V
  • The maximum voltage of contacts: 250 VAC, 125 VDC*
  • Maximum current: 10 A
• Optoelectronic insulation
• 6 LEDs signaling the activation of relays
• The dimensions of the board are 106 x 57 x 17mm
• Weight: 82 g
• Diameter of mounting holes: 3 mm

Description

The module allows control of the actuators consuming the current up to 10 A using the microcontroller’s ports or any development kit (including Arduino, Raspberry Pi, and STM32Discovery). Optical insulation separates the control signal from the part associated with the power of the relay, thereby providing work safety for the management system.

Connection

For proper operation, it is sufficient to connect the power of the relay coil and the digital control signal. Leads are the standard gold in strips with a pitch of 2.54 mm, which enables connection using the popular connecting cables.

The relay has the following pins

• VCC, DC+– power supply of the optocoupler
• GND, DC- – ground of the system
• IN1 … IN6– control inputs of the relay are activated by the low-status

Relay Contacts

• NC = Normally Closed side of the relay
• Center Terminal = Common terminal usually connects to the load power source
• NO = Normally Open side of the relay

1×3 Header

• JD-VCC = Opto-isolator power input.  Jumper to Vcc to run off same power supply as the logic (default mode).  If opto-isolation is desired, remove jumper and apply a separate 5V supply to this pin.
• VCC = Same as Vcc on the 1×10 header
• GND = Same as GND on the 1×10 header.  Can be used to connect ground of separate 5V power supply (if used)

Examples of application

• Driver of lighting
• The driver of the actuators
• Switch for electric devices, including motors
