Overview

Product Overview

The 4-Channel 5V Relay Module lets an Arduino or Raspberry Pi control up to four devices independently, acting like four GPIO-controlled on/off switches in one board. It is a great middle ground when you need more than a single relay but do not want a large multi-relay panel. Use it for multi-zone lighting, pumps, fans, solenoids, small automation panels, and test setups where you want simple, reliable switching from a 5V control system.

Questions & answers

Frequently asked questions

Does this relay module work with Arduino and Raspberry Pi?

Yes. It is designed so an Arduino or Raspberry Pi can control up to four external devices independently through GPIO-controlled relay channels. Use appropriate wiring for your controller and keep the relay board’s 5V power requirements separate from GPIO signal limits.

Is the relay module ready to connect?

Yes. ShillehTek supplies components pre-soldered, so the relay module is ready for jumper wiring instead of header soldering. You still need to connect power, ground, GPIO control inputs, and the switched device wiring correctly.

What voltage and interface does this relay module use?

The control side is a 5V relay module with four independent GPIO-controlled inputs. Each relay acts like an electrically operated on/off switch, letting a microcontroller control separate external circuits without directly powering those loads from its GPIO pins.

What projects use a 4-channel relay module?

A common project is controlling several small automation loads from one board, such as multi-zone lighting, pumps, fans, solenoids, or test fixtures. Each channel can be switched separately, so one controller can automate four devices or zones.

When should I choose a 4-channel relay board?

Choose this board when you need up to four independently controlled relay outputs but do not want a larger relay panel. If you only need one switched device, a single-channel relay is simpler; if you need more than four, use a larger module.

Solid relay module

Tested this relay module with a Raspberry Pi project for switching low-power devices. The board was easy to understand and the trigger behavior was helpful for setup. Nice little module for DIY electronics and prototyping.

Good Build Quality, Screw Terminals, Confusing Description

I ordered a 5V and a 24V, four-channel relay. They both came with the same SRD-05VDC-SL-C relay modules. One came as an eight-channel relay, despite having a label that it was a four-channel relay. I misunderstood the description and thought that the coil voltage was 24V. The build quality is decent, and the inputs have screw in terminal blocks, so it is more secure than simple pins. Overall, the build quality is good, but the description seems confusing if the voltage described is not the coil voltage. There also seems to be some quality inspection issues if the eight-channel relay I received was labeled as a four-channel relay.

Great Module

I got this module to experiment with my pi. So far, it's been working well without any issue and I am working on building an integration to be able to power cycle my network equipment and control it with the pi. It's been able to control the contacts without any issue and has worked just how I expected.

Good 4 channel relay.

Good relay module. Each relay is rated for up to 10 amps 250 volts AC. I have used many of these type of relay banks for automated switching of power to electrical outlets. These are handy for pretty much anything you want to toggle power to within spec. I have used them with raspberry pi's. These would not work well for higher power loads.The unit I received seemed to take some beating on its journey to the warehouse. The anti-static bag had a ton of indentations where the pins pressed up against the material. Given this all solder joints look solid and all 4 channels work well.

Good quality. Easy to use. An excellent value

This module can make controlling high current devices from logic inputs easy.You don't even need to solder anything and the connector blocks are well labeled and can take either flat or x screwdrivers. It even has mounting holes on the corners.Jumpers on the board let you choose active low or active high inputs for each of the relays.An LED shows that the board is powered and only draws a couple of milliamps.Each relay has an LED to show when it’s on. The relays draw about 90 mA when on.As you can see in one of the photos, a 5V input through a 1K resistor provides more than enough current to activate the relay drivers on the board. Nice!
