I would like to separately connect two pressure transducers to the 4-20ma input on the EMS.  The readout would be the same for both.  Can I connect these items through change over contacts on a relay?

If it's a sensor we support (for the EMS products), you can do exactly as you say.

Is it a first generation EMS or SkyView?

Am presently planning for a new Skyview installation. The transducers I wish to connect output 4-20ma and require 11 to 30 volts input. I presume that 12 volts would be available from pin 15 on the EMS to drive the transducer. Is this correct?

Yes, that's correct. Just know that that pin can support 1 fuel flow sender and one 4-20mA sender like you describe, but no more.
