Power supply for a 4-20 mA HART
®
The transmitter operates on 10.5 to 42.4Vdc at the terminal of the
transmitter. The DC power supply should provide power with less
than two percent ripple. Loops with a 250 Ω resistance require a
minimum of 16.6 V.
Note
The transmitter must have a minimum of 250 Ω to communicate
with a communication device. If you are using a single power supply
to power more than one Rosemount 3051 Transmitter, ensure the
power supply used and the circuitry common to the transmitters do
not have more than 20 Ω of impedance at 1200 Hz.
