Hello!

I understand that I cannot expand with further SEM modules if I use LEM03 on the main panel, but can I use this configuration:

Main panel + LEM03
1 RIO module on a bus?

Yes you can use the RIO to expand inputs and outputs. RIO are independent of LEM03
However remember that RIO Inputs cannot be used as security zones

Yes, of course. Thanks!
