three Moore Industries 535 controllers, one rosemount transmitter
(OP)
Can one Rosemount 3051 d/p transmitter supply signal to three Moore Industries 535 controllers? I have a boiler dearator with one level control valve, one make-up level control valve and one emergency dump valve. Each valve has a controller of its own. Can one Rosemount 3051 provide each controller with a level signal?

Check the data sheets for loop loading.

Make sure the loop supply can drive all three inputs in series (assuming a current loop).

With that in mind I suggested the 30 Volt power supply.

Or you could use a 4-20mA splitter, which produces two 4-20 signals. This Phoenix Contact model can drive 2 devices. each with 250 ohm input resistance and its input resistance is only 50 ohms:
