Communication Requirements “
᭛”:
BRAIN
Communication Distance;
Up to 2 km (1.25 miles) when using CEV polyethyl-
ene-insulated PVC-sheathed cables.
Communication distance varies depending on type
of cable used.
Load Capacitance;
0.22 µF or less (see note)
Load Inductance;
3.3 mH or less (see note)
Input Impedance of communicating device;
10 kΩ or more at 2.4 kHz.
Note: For general-use and Flameproof type.
For Intrinsically safe type, please refer to
‘Optional Specifications.’
HART
Communication Distance;
Up to 1.5 km (1 mile) when using multiple twisted
pair cables. Communication distance varies
depending on type of cable used.
Use the following formula to determine cable
length for specific applications:
L=
-
65 x 10

(R x C)
(C
f
+ 10,000)
C
Where:
L = length in meters or feet
R = resistance in Ω (including barrier resistance)
C = cable capacitance in pF/m or pF/ft
C
f
= maximum shunt capacitance of receiving
devices in pF/m or pF/ft
