Tips: Protective measures of solid state relays in terms of electrical noise
Generally speaking, solid state relays do not fail due to electrical noise unless they happen to falsely trigger during a possible high current surge during the line cycle. Oftentimes, failures due to noise are only temporary, such as opening when a solid state relay should be closed, and vice versa.Noise by its nature is difficult to define, it is created by the randomness of contact bounce and motor commutator arcing, etc.
Noise, more correctly defined as Electromagnetic Interference (EMI), affects solid state relays by sending signals into sensitive parts of the circuit, such as thyristors.A built-in snubber RC network across the output can effectively reduce sensitivity to noise, especially at lower frequencies. This is standard for CII AC relays.
