PEPPERL+FUCHS Resistance Repeater KCD2-RR-Ex1
1-channel isolated barrier < 24 V DC supply (Power Rail)
Resistance and RTD input (Pt100, Pt500, Pt1000) < Resistance output
Accuracy 0.1 %
Line fault detection (LFD) for Pt100 < Housing width 12.5 mm
Up to SIL 2 acc. to IEC 61508
Function
This isolated barrier is used for intrinsic safety applications.
It transfers resistance values of RTDs or potentiometers from hazardous areas to safe areas.
A 2-, 3-, or 4-wire technique is available depending on the required accuracy.
The input card of the control system measures the same load as if it were connected directly to the resistance in a hazardous area.
