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.

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.


Pin Diagram


  1. Low power consumption
  2. Long-lasting
  3. Optional I2c address
  4. Advantages over mechanical relays:
    1. Solid-state relays have many faster-switching speeds compared with electromechanical relays and have no physical contacts to wear out
    2. Totally silent operation
    3. No physical contacts mean 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. Operations that require low-latency switching, e.g. stage light control
  2. Devices that require high stability, e.g. medical devices, traffic signals
  3. Situations that require explosion-proof, anti-corrosion, moisture-proof, e.g. coal, chemical industries.
