WHAT IS SSR SOLID STATE RELAY?
Summary information without going into much detail; For the SSR ( Solid State Relay ), the mechanical contactless electronic switch can be called an electronic relay. Control low current with CMOS, TTL, ETC. can be done. Triac, thyristor, Mosfet, igbt can be used for power control. For insulation, Optoisolator is usually used as Opto Coupler. For information about the Opto Coupler, see: What is Opto Coupler? How does it work? What is Triac in addition to varieties, What is thyristor?
SSR Solid state relays are increasingly being used because of their advantages, because the SSR does not have corrosion, no mechanical parts that are subject to wear, contact spark, etc. For example, The 8-legged DIP integrated sheath has low-power SSR relays.
The control voltage is in a wide range. High galvanic isolation between the control circuit and the load is low in noise ratio. Solid-state relays have fast switching speeds compared to electromechanical relays.
The SSR Solid State Relay has many advantages but disadvantages. When closed, there is higher resistance (generating heat) and electrical noise. The voltage-current characteristic is non-linear (not fully resistant ), which in some way disrupts switching waveforms. Some SSR designs require a connection compatible with polarity. Electromechanical relays are not affected by polarity.
