hello everyone. 

I'm busy putting up a small facility with a 2x OBA7 (230RCe) and 2x DM16
I have 3 switches to control (with an LED that indicates if the light is on or not ...) 
So I use an output to control with the Logo an LED (230v in the switch) 

The problem: there is a residual 1 volt output on the Logo!, Is this normal?

And another question : 
I have 4 automatic switches (motion sensor) to be connected to the logo!, What are your tips?

Thank you very much, and sorry for my english ...

Dear GMo,

I couldn't understand your question well but if you mean " There is 1 volt on output at off state" Yes it is normal and if you don't need this for your application you can pull down by adding a resistor.

For your second question: What is the wiring configuration of the motion sensor? (For example consider it is shadow sensor having 3 wires: wire-1 is +24VDC, wire-2 is OUT, wire-3 0V.) Or just attach your motion sensor catalog.

Regards

Thank you for the response.

I'm surprised that there 1 volt on the TOR output of 230 Rce Logo!  (R of Relay)
On documentation, it's not specified, but, it's OK, I put a resistor ...

For the motion detector, I have this : 
It's a 2-fire without neutral.  but the minimum is 40w ...
Tomorow, I buy a capacitor X 2,5 kV 100nf, and I test it ...

Best Regards
