Function
This isolated barrier is used for intrinsic
safety applications. It drives a voltage or
current signal from the safe area to I/P
converters, electrical valves and
positioners located in the hazardous
areas.
According to a unique ordering code, this
barrier is designed to provide various
inputs and outputs of voltage and current.
Ordering example: Input 0 V ... 10 V and output 4 mA ... 20 mA is code number 8
Model number is KFD2-CD-Ex1.32.8
The values shown in parentheses are subsets of the larger signal range.
