About PEPPERL+FUCHS KFD2-STC4-Ex2 SMART Transmitter Power Supply

PEPPERL+FUCHS KFD2-STC4-Ex2 SMART Transmitter Power Supply

• 2-channel isolated barrier
• 24 V DC supply (Power Rail)
• Input 2-wire SMART transmitters
• Output 0/4 mA ... 20 mA
• Terminals with test points
• Up to SIL 2 acc. to IEC/EN 61508

This isolated barrier is used for intrinsic safety applications.

The device supplies 2-wire SMART transmitters in a hazardous area.

It 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 safe area and are transferred bi-directionally.

Reliable Isolation & Protection

This SMART transmitter power supply offers dependable isolation between field devices and control systems. Its built-in short-circuit and overload protection help safeguard both connected sensors and your automation infrastructure, reducing maintenance efforts and downtime.


Flexible Signal Transmission

With bi-directional signal transmission and compatibility for analog 4-20 mA and HART protocols, the KFD2-STC4-Ex2 provides seamless communication in various process control applications. Each of its two channels can operate independently, expanding system versatility.


Easy Installation & Operation

Housed in a durable polycarbonate enclosure and equipped for DIN Rail mounting, this device simplifies installation. Its automatic grade functionality and diagnostic LED indication enhance operational efficiency while facilitating easy monitoring and troubleshooting.
