PROFIBUS PA
Use a twisted, shielded two-wire cable, preferably cable type A
For further information on the cable specifications, see Operating Instructions BA00034S
"PROFIBUS DP/PA: Guidelines for planning and commissioning", the PNO Guideline 2.092
PROFIBUS PA User and Installation Guideline" and IEC 61158-2 (MBP).
FOUNDATION Fieldbus
Use a twisted, shielded two-wire cable, preferably cable type A
For further information on the cable specifications, see Operating Instructions BA00013S
"FOUNDATION Fieldbus Overview", FOUNDATION Fieldbus Guideline and IEC 61158-2 (MBP).
Start-up current
• Analog electronics:: 12 mA
• HART: 12 mA or 22 mA (selectable)
Residual ripple
No influence on 4 to 20 mA signal up to ±5 % residual ripple within the permitted voltage range
[according to HART hardware specification HCF_SPEC-54 (DIN IEC 60381-1)].
Influence of power supply
≤0.001 % of URV/V
Overvoltage protection
(optional)
The device can be fitted with overvoltage protection. The overvoltage protection is mounted at the
factory on the housing thread (M20x1.5) for the cable gland and is approx. 70 mm (2.76 in) in
length (take additional length into account when installing). The device is connected as illustrated in
the following graphic.
For details refer to TI01013KDE, XA01003KA3 and BA00304KA2.
