System Components
KFD2-STC5-Ex1
This isolated barrier is used for intrinsic safety applications.
The device supplies 2-wire and 3-wire SMART transmitters, and can also be used with 2-wire
SMART current sources.
The device transfers the analog input signal to the safe area as an isolated current value.
Digital signals may be superimposed on the input signal in the hazardous or non-hazardous
area and are transferred bidirectionally.
The device has bidirectional HART communication.
KFD2-STC5-1
This signal conditioner provides the galvanic isolation between field circuits and control
circuits.
The device supplies 2-wire and 3-wire SMART transmitters, and can also be used with 2-wire
SMART current sources.
The device transfers the analog input signal as an isolated current value. Digital signals may be
superimposed on the input signal on the field side or on the control side and are transferred
bidirectionally.
The device has bidirectional HART communication.
M-LB-2000, M-LB-5000
Surge protection barriers for DIN mounting rail as per IEC 60715, suitable for protecting
electronics against destruction as a result of overvoltage.
•
M-LB-2000: surge protection system for the hazardous or non-hazardous area
•
M-LB-5000: modular surge protection system with or without diagnostic function for the
hazardous or non-hazardous area
