explain all about a solid state relay.?

Answer 1

in a solid state atoms in a substance are held in closer to each other which gives it a strong feel to it

Answer 2

A solid state relay uses semiconductors (transistors, SCRs, FETs) as switches rather than mechanical components. From Wikipedia:

"A solid-state relay (SSR) is a solid state electronic component that provides a similar function to an electromechanical relay but does not have any moving components, increasing long-term reliability. The tradeoff comes from the fact that every transistor has a small voltage drop across it, typically 0.7 vdc. If the SSR has a load of 10 amps, there is 7 watts of heat to dissipate. A hundred amp load would require fans to be mounted to shed 70 watts of heat."

Answer 3

sturdy state relays are in many cases meant for switching one hundred twenty/240V AC a lot like heaters. they are meant to change around the 0 crossing of the AC cycles. many times the switching element is a triac gadget. it quite is super for heaters or lamps, not so super the place inductance is present day, like an AC motor. whilst switching a DC motor, it probable does not paintings in any respect, very in all probability staying "ON", yet actually those adult males have been impolite and uncouth, and can inspire others extremely of attempting to instruct how clever they are (or at the instant are not). the define I gave is how they are often, yet not all of them are this way i've got faith. the answer for switching a DC motor many times is composed of transistors, now and returned in a configuration that helps reversing, and many times the association is so the transistors could be switched rapidly to selection the value (pulse width modulation PWM). seek for H bridge for information. The hyperlink shows the elementary theory, the place there are 4 controlling indicators from a good judgment source using the comparable grant voltages in this occasion. each and every transistor is the two on or off in accordance to its administration sign. present day could be exceeded in the time of the motor in the two path. the 2d hyperlink shows an user-friendly change the place the motor can not be reversed (parent 9).

Answer 4

it has 4 terminals
2 for input signal 0-30 dc volts
2 for out put as normal open
when we have input signal the normal open become close and the signal pass throughout the out put term.
SSR is classified by ampers

Answer 5

u run the relay with s**t in ur hands

Answer 6

gp4rts is right on the money

Answer 7

is this your HOMEWORK?
dont know the answer anyway

Answer 8
