    Tips: Solid state relays' advantages and disadvantages

    Solid state relays work reliably and have a long life, no noise, no spark, no electromagnetic interference, fast switching speed, strong anti-interference ability, and small size, impact resistance, vibration resistance, anti-explosion, moisture proof, corrosion resistance, compatibility with logic circuits such as TTL, DTL, HTL. They can directly drive high-current load with tiny control signals.
    The main disadvantage is the existence of on-state voltage drop (corresponding cooling measures needed), off-state leakage current, common use in AC and DC conditions, fewer contact sets, as well as poor indicators including overcurrent and overvoltage and voltage rise rate, current rise rate, etc.
