Pepperl+Fuchs KLD2-PR-Ex1.IEC. Manual page 20

Power repeater / power supply according to IEC 61158-2
Total line length = length of the trunk line + total of spurs
The total maximum line length for non-Ex applications is 1900 m.
Pepperl+Fuchs GmbH offers two different power supplies:
1. KLD2-STR-1.24.400.IEC, field bus power supply current with 400 mA current for
non-Ex applications
2. KLD2-STR-NI1.13.225.IEC, field bus power supply with 225 mA supply current in
"Non Incendive" ignition protection class.

a.The actual number of field devices on a bus segment depends on the actual current consumption of the slaves. The specified numbe r of field devices is only
reached if the current consumption for each field device is 10 mA.
b.The actual line length depends among other things on the cable that is used and the number and distribution of slaves.
c.For max. output current and cable type A [0.8 mm² (18 AWG)]
To determine the exact maximum line length, please refer to the section "Voltage cal-
culation and line length" on
Subject to reasonable modifications due to technical advances.
