Note: From February 2020 onwards, the module comes with a logic low circuit.

The Relay breakout board is a convenient board to be used with 5V microcontrollers such as SK40C, SK28A, Arduino, SKds40A, SK18B. You can easily use 5V signal to control the relay. Three inputs:

  • VCC = 5V is needed
  • GND = Common Ground, 0V
  • IN = Control signal need to be 5V 0V to activate the Relay (Active Low)

The relay terminals (COM, NO, and NC) are brought out using a 3-way screw terminal. On-board relay is rated at 10A. It can be used in many applications: controlling high voltage, high current loads such as motor, solenoid valves, lamps, and AC load. It also comes with 2 LEDs to indicate the status power (VCC) and the status of the relay.

Note: This is an active-high active-low device, which means logic high (5V) low (0V) at pin IN will trigger the relay.


  • Digital output controllable
  • Compatible with any 5V microcontroller, SK40C, SK28A, SK18B, SKdsPIC, Arduino
  • Single relay board

  • Max. Allowable Power Force: 800VAC/240W
  • Logic: Active Low (Feb 2020 onwards)

Packing List:

  • 1 x Single Channel 5V Relay Breakout Board
Just to clarify the VCC pin is not in the middle between IN and GND right? Plan to design PCB ( Syeikh Abdul Aziz Syeikh Ahmad Ridhoudhi, 21/09/2020 )
Not answered yet.
From Description, Features, It stated:-
Maximum switching voltage: 250VAC/110VDC
But, from picture
looks like 250V AC / 3V DC
Which one is the correct specification?
( M.H.M., 11/01/2020 )
Hi, it is correct for both. For further clarification, do email to support@cytron.io Thanks :)
Hi, i have an "auto switch " application i want to build. The load/electric appliance that i try to add the "auto switch" can vary from 5vdc to 12 to 18vdc. Can i use this 30vdc relay, so no matter the load, the relay will be able to handle? ( 5 or 12 or 18 or 24VDC relay, 03/12/2019 )
Hi, yes you can do so. Thanks :)
Can this relay connect and control between a 5V DC supply and a 5V DC load (1A) ? ( fidaa, 15/11/2019 )
Hi, yes it can do so. Thanks :)
Do you have the cad file ? ( Lam, 11/11/2019 )
Hi, we're sorry we do not have it at the moment. Thanks :)
free gift? my birthday tomorrow ? have? ( fitry jalil, 21/05/2019 )
Hi, sorry we don't have that.
Can the Arduino digital pin (3.3V) trigger the relay? ( Ng, 23/03/2019 )
Hi, sorry the control signal needs to be 5V to activate the Relay.
Hi i want to ask, can this be triggered by raspberry pi gpio pin? if not, can you recommend any relay that can? ( andy sau, 05/08/2017 )
Hi, this product is discontinued. You can consider to use Raspberry Pi Relay Board v1.0. For further questions, please visit to our technical forum as this session is only for short inquiry. Thanks.
how is this suppose to connect to SK40? ( carmen, 13/06/2016 )

Hi. You can refer to Getting Started Guide under " Attachment" tab. Thanks :)

What type transistor used in this relay? ( shahfiee, 24/03/2016 )

Hi, It is NPN type transistor. Thanks. :)
