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
Barnabás
