FAQ:

Q: Why do we use solid state relay?

A: Generally,SSR relay are used for switching purpose i.e. … It is used to control the power i.e. … They are also use to drive electric heaters to control the temperature. SSR cab be used as a latch which is useful in case of kettles. In communication lines,photocoupler SSR relay are used to eliminate relay driving current flowing through it.

Q: What is the definition of a solid state relay?

A: SSR Definition: A solid state relay may be defined as an electrical switch that changes its state when an external voltage is applied to it. Solid state relay has a capability to control a larger load current or voltage.

Q: What is a solid state relay module?

A: Solid-state relay. A solid-state relay ( SSR) is an electronic switching device that switches on or off when a small external voltage is applied across its control terminals. SSRs consist of a sensor which responds to an appropriate input (control signal), a solid-state electronic switching device which switches power to the load circuitry,…
