Technical data<strong>KCD2</strong>-<strong>RR</strong>-<strong>Ex1</strong>Additional informationFunctionWhen a signal converter, a DCS or PLC is connected to terminals 5, 6, 7, and 8 (control side), the measuring current istransferred to terminals 2 and 4 (field side). The resulting voltage at terminals 1, and 3 is transferred to terminals 5, 6, 7, and 8.In the case of fast multiplex input cards, transmission problems might be experienced in connection with low resistance valuesand/or high sensor currents.

Technical data<strong>KCD2</strong>-<strong>RR</strong>-<strong>Ex1</strong>Line Fault Detection (LFD)The output will indicate less than 10 Ω or greater than 400 Ω for a lead breakage at terminals 1, 2, 3 or 4 for measuring currentof less than or equal to 1 mA i.e. out of range for Pt100.AccessoriesPower feed module KFD2-EB2The power feed module is used to supply the devices with 24 V DC via the Power Rail. The fuse-protected power feed modulecan supply up to 100 individual devices depending on the power consumption of the devices. A galvanically isolated mechanicalcontact uses the Power Rail to transmit collective error messages.Power Rail UPR-03The Power Rail UPR-03 is a complete unit consisting of the electrical inset and an aluminium profile rail 35 mm x 15 mm. To makeelectrical contact, the devices are simply engaged.Profile Rail K-DUCT with Power RailThe profile rail K-DUCT is an aluminum profile rail with Power Rail insert and two integral cable ducts for system and field cables.Due to this assembly no additional cable guides are necessary.Power Rail and Profile Rail must not be fed via the device terminals of the individual devices!AttentionRelease date 2010-11-22 14:41 Date of issue 2011-04-04 190247_ENG.xmlSubject to reasonable modifications due to technical advances.Copyright Pepperl+Fuchs, Printed in GermanyPepperl+Fuchs Group • Tel.: Germany +49-621-776-0 • USA +1-330-4253555 • Singapore +65-67-799091 • Internet www.pepperl-fuchs.com 5
