What is a solid-state relay?
A solid-state relay (also known as an SSR, SS relay, SSR relay, or
SSR switch) is an integrated non-contact electronic switching
device that is tightly assembled from an integrated circuit (IC)
and discrete components. According to the switching characteristics
of electronic components such as switching transistors,
bidirectional thyristors, and other semiconductor components, the
SSR can switch the "ON" and "OFF" states of the load very quickly
through the electronic circuit, just like the function of
traditional mechanical relays with the previous compared to "coil
reed contact" relays (i.e. electromechanical relays) (EMRs), there
are no moving mechanical parts inside the SSR, and there is no
mechanical action during the switching process of the SSR.
Therefore, solid-state relays are also called "non-contact
switches".
The main advantages of solid-state relays are as follows:
● Semiconductor components act as switches for relays, which are
small in size (compact) and long in life (long life).
●Better electromagnetic compatibility than EMR - Anti-radio
frequency interference (RFI) and electromagnetic interference
(EMI), low electromagnetic interference, and low electromagnetic
radiation.
● No moving parts, no mechanical wear, no action sound, no
mechanical failure, and high reliability.
● No spark, no arc, no burning, no bounce of contacts, no abrasion
between contacts.
● With the function of "zero voltage switching, zero current
shutdowns", it is easy to realize "zero voltage" switching.
● Fast switching speed (SSR switching speed is 100 times that of
ordinary EMR), high working frequency. High sensitivity, the low
power control signal (SSR can directly drive high current load
through small current control signal), compatible with logic
circuit (TTL, CMOS, DTL, HTL circuit), easy to realize multiple
functions.
●Usually made of packaging insulation materials, with good moisture
resistance, mildew resistance, corrosion resistance, vibration
resistance, mechanical shock resistance, and explosion-proof
performance.
