• The supply voltage VCC 5 V
• Activated via low state
• Relay SRD-05VDC-SL-C (documentation)
  • Coil voltage: 5 V
  • The maximum voltage of contacts: 250 V AC, 110 VDC*
  • Maximum current: 10 A
• Optoelectronic isolation
• 16 leds that signal the activation of relay
• Tile sizes 180 x 90 mm
• Weight: 225 g
• Diameter of mounting holes: 3 mm

* Maximum contact voltage depends on the type of load - details inthe documentationtab. 7. Contact Rating.

The module allows to control the actuators consuming the current up to 10 A using the microcontroller's ports or any starting set (includingArduino,Raspberry PiandSTM32Discovery). Optoinsulation seperates the control signal from the part associated with the power relay, thereby providing work safety for the control system.

The product is compatible with Arduino

For relay control, onlyu a digital control signal from leads of the Arduino is needed.

For proper operation, connect the power of the relay's coil and the digital control signal. Leads are the standardstrap goldpinwith pitch of 2.54 mm, which enables connection with the connecting cables.

The relay has the following leads

• 5V, DC+- power of optoisolation
• GND,DC-in- weight of the system
• IN1 ... IN16- inputs controlling the relays activated by low state
• Connector KF (ARK)- the relay's contacts are connected in accordance with the pattern on the board of the module.

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