Communication Requirements “
”
(Safety approvals may affect electrical require-
ments.)
BRAIN
Communication Distance
Up to 2 km (1.25 miles) when using CEV polyethylene-
insulated PVC-sheathed cables. Communication distance
varies depending on type of cable used.
Load Capacitance
0.22
F or less
Load Inductance
3.3 mH or less
Input Impedance of communicating device
10 k
or more at 2.4 kHz.
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= –

Where:
L = length in meters or feet
R = resistance in

C = cable capacitance in pF/m or pF/ft
C
f
= maximum shunt capacitance of receiving devices in
pF/m or pF/ft
