About the relays
-
Hi,
I'm thinking about using an L403 for controlling a large number of blinds (apart from other building automation duties) with 2 relays per blind motor.
Before going with this, I'd like to know a bit more about the relays on board, so that I can assemble a long-lifespan solution:- What is their exact type? Could you please link their detailed datasheet?
- Is it difficult to replace them, shall any of them die in a couple of years?
- Is there feedback to the control software regarding the actual position of the relay?
Thanks

Hi @barnabás-králik,
- Relays are this one: https://www.tme.eu/en/details/ftr-f3aa024e-ha/miniature-electromagnetic-relays/fujitsu/
- yes, relays are difficult to replace and replacing them by yourself means losing the warranty
- there is no feedback about the physical state, e.g. via secondary terminals
Best regards,

Why not go for TCP-IP solution, i use a Kincony kc868-h32, a 32 relay solution, that you can steer the relays true a url link command, works fine for me.
There are similar solutions more hobby orientated, and more pro, over Modbus, serial and TCP-IP, there are also 2/4/8/16 solutions out there, so that you can have your relays close by what you wane control, and only have to run a network or serial cable to the relay unit.
