What are the benefits and usefulness of solid state relays?

Answer:

Its role is: solid-state relay is a non-contact function of the electronic switch, in the switch process without mechanical contact parts, solid state relays in addition to the same function with the electromagnetic relay, but also has a logic circuit compatibility, resistance to mechanical resistance, The installation location is unlimited, has a good moisture-proof anti-mildew anti-corrosion performance, in the explosion and prevent ozone pollution performance is also excellent, low input power, high sensitivity, low control power, good electromagnetic compatibility, low noise and high operating frequency Features. Has been widely used in computer peripheral interface equipment, temperature control, speed control, dimming, motor control, electric furnace heating control, power petrochemical, medical equipment, financial equipment, coal, instrumentation, traffic signals and other fields.

solid state relay        The advantages are: 1) high life, high reliability: solid state relay without mechanical parts, solid devices to complete the contact function, because there is no movement of parts, it can work in high impact, vibration environment, due to the composition of solid state relay Of the inherent characteristics of the components, determines the solid-state relay long life, high reliability. solid state relay

(2) high sensitivity, low control power, good electromagnetic compatibility: solid-state relay input voltage range is wide, low drive power, compatible with most of the logic integrated circuit without a buffer or drive. (3) rapid conversion: solid-state relay because the use of solid devices, so the switching speed from a few milliseconds to a few subtle. (4) small electromagnetic interference: solid state relay does not enter the "coil", no contact arcing and bounce, thus reducing the electromagnetic interference. Most AC output solid state relays are a zero voltage switch that turns on at zero voltage and turns off at zero current, reducing the sudden disruption of the current waveform, thereby reducing the switching transient effect.
