What are solid state relays?
In electrical terms, a relay is a relatively simple switching
device that’s used to automatically close or open a set of contacts
between two circuits. This process is triggered by an electrical
input or control signal of some kind, in response to which the
relay switch usually moves from an ‘off’ to an ‘on’ position.
In so doing, the relay closes (or, less commonly, opens) a specific
set of contacts, thus completing (or breaking) the circuit(s). In
most cases, when the electrical relay device is receiving no
signal, the contacts are open and the circuit is effectively
incomplete. When an electrical control signal is sent to the relay
terminals, it triggers a physical response in the relay switch,
typically causing it to close those contacts and complete the
circuit as required.
In a standard relay, this process is electromechanical (hence these
relays being referred to by the acronym EMRs). In other words, an
electrical control signal triggers a mechanical response in the
relay. The standard mechanical relay switch is therefore composed
of key moving parts, and it’s these parts that physically change
position in order to open/close the contacts and complete or break
the circuit as required.
By contrast, a solid state relay has no mechanical or moving parts.
As electrical components, SSRs are widely used to perform much the
same on/off, open/close functions as standard relays, but a solid
state switch does so entirely without any physical movement within
the relay itself. (We’ll look more closely at how this works in the
next section of this guide.)
Solid state relays can be designed to operate either based on AC or
DC input currents, depending on the specific model and
applications. Common voltages for DC input include 5V, 12V and 24V
DC solid state relays, while widely available examples of AC solid
state relays are often based around 120V or 240V AC input.
The term ‘solid state relay’ is actually a fairly generic one, and
can, in fact, refer to all manner of different relay components and
configurations used to achieve the basic on/off switching function.
Many of these configurations will be designed around specific
industries or applications. Solid state relays made for automotive
use, for example, tend to be optimised for plug-and-play
installation methods and resilience against harsher environmental
conditions (anti-vibration, over-voltage protection, polarity
reversal and short circuit protection) than you’d typically
encounter in, say, industrial or production applications.
