If we use the relay for electrical outlets, take into account output power of the relay.
If it is a large consumer, it is important that the relay first activates the contactor and only then the consumer.
Unlike SSR, with mechanical relays it happens that the relay "stuck" due to higher voltage.
In a "normal open" situation with a mechanical relay, if no signal is given to it and it still passes current, it is probably also a "stuck" relay.
If it is a SSR and if burning occurs, the temperature is always increased on the relay and an unpleasant smell is felt.
With a mechanical relay, it is completely irrelevant where the signal is connected and where GND is connected. At SSR it is very important. If we connect it incorrectly, the SSR will burn out.
It is important that the electric outlet and relays are connected to the application correctly.
The application should be used to properly adjust the scenario. An important relief is that several consumers can be switched on at the same time or switched off according to a special regime.
All relays work according to the principle of "input" and "output", as well as "and" and "or" conditions. During automation, we use exactly these possibilities with a note, with one scenario we can activate and deactivate several relays at the same time.
