When Mounted at the end of the PCB it offers over 2kV
Isolation from the Digital Circuits. The Output 230V signals
NO-NC, can control Light Loads like the Coil of a Big 230V
Relay also called contactor.
It could be Mounted on a PCB by soldering or a Plugin Base.
It is better to have Crimped connections or Terminals. A very
good quality spring Loaded Socket may also work but it has to
be rated for many operations. Things like Nickel Alloy Plated,
Beryllium Copper were the Materials Jargon. A contact
resistance in the Terminals, a mismatch of alloys,
electrochemical reactions, Corrosive Fumes, Brine or High
Humidity can build a Loose connection into a Dangerous
Not only the Functionality of the SSR will be affected in a
Sparking Contact, but a Risk of a Fire Developing. When
Inflammable Materials or Volatile Liquids are Present Nearby,
the risk is even greater.

PCB SSR Module
This is a PCB Mount SSR for Control of a Small AC load like a Lamp or a Contacter. It has Optical Isolation and has a Thyristor for output. The MOC3041 A zero crossover optical triac driver is used here. The footprint is very small, many can be stacked in one small PCB.

This is the enclosure for the Encapsulated Mini RTD PT100
Transmitter and also Solid State Relays - SSR.
Potted, Encapsulated in epoxy, hermetically sealed. It has a Nickel Plated Aluminum Plate insert molded. For removing heat from BTA41600.
The plastic is a fire retardant high temperature grade. The
epoxy is ciba araldite, fine alumina is filler. A transparent
terminal cover for safety. It costed me an equivalent of
600-700 USD for tooling plastic parts.
