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 - 8-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.

According to different application scenarios, we have prepared a series of solid state relays for you.

Grove - Solid State Relay V2

Grove - 2-Channel Solid State Relay

Grove - 4-Channel Solid State Relay

Grove - 8-Channel Solid State Relay

Due to the leakage current, we do not recommend you to use this relay with low power consumption applications.

Features

• Low power consumption.

• Long lasting.

• Optional I2c address.

• Eight-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.

  
  

• Disadvantages:

  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.
