Advantages over mechanical relays: Solid-state relays have much faster switching speeds compared with electromechanical relays, and have no physical contacts to wear out Totally silent operation 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 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 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 channel Disadvantages: When closed, higher resistance (generating heat), and increased electrical noise When open, lower resistance, and reverse leakage current Only works for AC load 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 More information:  | | Kit Classification: | Shield | Featured Device: | G3MC202P | Kit Name: | Grove - Solid State Relay V2 |
