For starters, solid state relays offer faster switching times than mechanical relays,
as these depend on the amount of time needed for the light emitting diode (LED)
to turn off and on. This means that the electrical currents supplied to
machinery and equipment can deliver faster, therefore increasing machine
efficiency. Aside from this, these relays are more preferred by a lot of
companies because they are more economical and efficient in terms of
maintenance costs.
Solid state relays have no movable parts, so this means that
there are no components exposed to daily wear and tear. Mechanical relays need
parts replacement every so often because the movable parts can expose
themselves to wear and tear brought about by the on-off switching process.
Industries that need the use of explosives, such as mining, benefit from relays
because they do not spark when the current triggers on and off. They also offer
reduced electrical noise during operations, making them excellent choices for
enclosed spaces where even the slightest noise magnifies several times. In
addition, these types of relays are not as sensitive as mechanical relays when
speaking of various factors that affect a production area. These factors
include vibration, mechanical shock, and humidity.
