2Overview
2.1 Application
The devices of the K-System from Pepperl+Fuchs are used to transmit signals between field
devices and the process control system or control.
Devices with the "Ex" code in their type identifiers are suitable for connection to field devices in
the hazardous area. The field current circuits of these devices are intrinsically safe and are
galvanically isolated from the not intrinsically safe circuits. The devices thus represent an
electrical isolation between the hazardous area and the safe area within a system.
Devices without an "Ex" code can be used for signal transmission between field devices in the
safe area and the process control system or the control.
This symbol indicates a warning about a possible danger.
Failure to observe this warning may result in personal injury or death, or property
damage or destruction.
This symbol warns of a possible fault.
If the instruction given in this warning is not heeded, the device and any systems or
plants connected to it could develop a fault or even fail completely.
This symbol brings important information to your attention.

If a current output is operated as a sink, the voltage across the terminals must be between 5 V and
30 V. An additional resistance is only required if the voltage is above 16.5 V. The resistance must
be between (U - 16.5 V)/0.0215 A and (U - 5 V)/0.0215 A (see diagram).
Example: U = 24 V
(24 V - 16.5 V)/0.0215 A = 350 
