Hello experts

   Can i use one safety output to control two valves at the same time ?

  the order number of the output number is 6ES7138-4FB03-0AB0 

 i check the output current  is 2A. and the each valve need 1.15A.

 Can i connect the wires like the picture?

hi winterwang, 

generally it works to connect two valves with one F-DO. 

But the current you mentioned is to high. 1.15A per valve would be 2.3A with both. That is too much.

Yes , i know the current is a little high...

I saw the manual , it says: the normal current is 2A, and the max. is 2.4 A. 

ah, okay,

so have a try!

paralell switching is also mentioned in the manual, page 194

its better use it by a realy in your cabinet

WATCH IT!  

If it is a safety Output, any relay needs (according to safety level) a monitoring!

So you will need additional Inputs and software for any relay!
