Communication Requirements “◊”
(Safety approvals may affect electrical
requirements.)
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 μF or less
Load Inductance
3.3 mH or less
Input Impedance of communicating device
10 kΩ 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= –
65 × 10 6
(R × 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
EMC Conformity Standards ,
