Can a Satel CA10P handle home alarm and lighting automation, or do I need an Integra/PLC, and how should the relay output be wired?
The CA10P is not enough for this kind of lighting automation; an Integra can do light control and similar functions, preferably in a 64-zone version or WRL [#15451029] You do not need a PLC if you use Satel relay/output modules such as INT-IORS or INT-O to switch 230V AC loads [#15463824][#15463872] Satel low-current outputs are ground-controlled and provide a constant 12V, so the relay coil should be driven from the output with a diode in parallel to protect the panel [#15453219][#15462898] If you only have twisted pair at the switches, you can still use it with the bus as long as you do not put dTM and CKM/DT1 and CK1/DT2 and CK2 signals on the same pair [#15451458] For bistable switching, one option discussed is a two-coil bistable relay or a zero-voltage bistable relay module like PBM-05 [#15490029][#15482434]
On the website they have a tab: "Contract manufacturing".
And I guess it's not a problem to pack the PBM-05 electronics into a can housing...?!
Especially since the subject is brought up here because there might be a "market niche" (switchable element for the can, controlled by low voltage ....po twisted pair).
"Sell" them the idea...hihi...for the small dozen pieces you need
For this you need a base - so it will be big anyway (most often the base is a TS35 rail component). The second problem is switching control: you need to feed the correct polarity for 'on' and the opposite for 'off'.
but why do I need a can holder? I only need to bring the connectors out to the PCB and it will fit somehow.
worse, the integra has no possibility to change polarity...
Therefore, it is better to look for two-coil bistable relays, e.g.http://www.piekarz.pl/pl/?item=45074
Two signals from the Integra: "on" - "off" to two coils.
i don't know why, but I was convinced that every additional pulse on the coil turns the relay on/off.
A two-coil is also a bit of a bummer because it takes up the outputs, and I still have to count the input from the switch so I can manually turn on the light too o_0
