Description of Current/Voltage Driver

This signal conditioner provides the isolation for non-intrinsically safe applications.
The device drives a current signal from the control side to I/P converters, electrical valves and positioners.
The max. voltage drop at the input is 4 V DC, allowing for the connection of several KFD2-CD-1.32 repeaters due to the low voltage drop in order to maintain multiple galvanically isolated outputs (signal duplication).
