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?
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?
