Instead of using coil, packaged solid-state relays(SSR) use power semiconductor devices such as thyristors and transistors, which provide a much faster switching speed than the mechanical relays. The Grove - 4-Channel Solid State Relay is based on the high-quality G3MC202P module, which allows you to use a 5VDC to control MAX. 240VAC. With the help of Grove interface, it becomes very convenient to use the SSR with your arduino.

We use an on-board STM32F030F4P6 to control the channels separately. The command from Arduino or other boards is transmit via the I2C interface, the on-board STM32F030F4P6 will parse the command, so that you can control the switch you want.


1*Please be careful when working with high voltage AC load, please do not operate with power on.

2*This relay only works with AC load, if you use DC load, once the relay is turned on, it will always stay on.

3*Due to the leakage current, we do not recommend you to use this relay with low power appliance.


  • Low power consumption.
  • Zero Cross
  • Long lasting.
  • Optional I2c address.
  • Four-channel independent control.
  • Advantages over mechanical relays:
  • 1.Solid-state relays have much faster switching speeds compared with electromechanical relays, and have no physical contacts to wear out.
  • 2.Totally silent operation.
  • 3.No physical contacts means no sparking, allows it to be used in explosive environments, where it is critical that no spark is generated during switching.
  • 4.Increased lifetime, even if it is activated many times, as there are no moving parts to wear and no contacts to pit or build up carbon.
  • 5.Compact, thin-profile SSR of monoblock construction with an all-in-one lead frame incorporates a PCB, terminals and heat sink, which is much smaller than mechanical relays, and can integrate more channels.


  • 1.When closed, higher resistance (generating heat), and increased electrical noise.
  • 2.When open, lower resistance, and reverse leakage current.
  • 3.Only works for AC laod.

Typical Applications

  • Operations that require low-latency switching, e.g. stage light control.
  • Devices that require high stability, e.g. medical devices, traffic signals.
  • Situations that require explosion-proof, anticorrosion, moisture-proof, e.g. coal, chemical industries.
