Specifications and reference data
A.2.3
Service
Liquid, gas, and vapor applications
A.2.4
4–20 mA (Output Code A)
Output
Two-wire 4–20 mA, user-selectable for linear or square root output. Digital process variable
superimposed on 4–20 mA signal, available to any host that conforms to the
HART
protocol.
Power Supply
External power supply required. Standard transmitter (4–20 mA) operates on 10.5 to 55 Vdc
with no load.
Load Limitations
Maximum loop resistance is determined by the voltage level of the external power supply, as
described by:
A.2.5
F
OUNDATION
fieldbus (output code F) and Profibus (output
code W)
Power Supply
External power supply required; transmitters operate on 9.0 to 32.0 Vdc transmitter terminal
voltage.
Current Draw
17.5 mA for all configurations (including LCD display option)
Voltage (Vdc)
Load (
O
hms
)
Communication requires a minimum
loop resistance of 250 ohms.
(1)
For CSA approval, power supply must not exceed 42.4 V.
Max. Loop Resistance = 43.5 (Power Supply Voltage – 10.5)
