Pepperl Fuchs 1-channel Intrinsic Safety Barrier Isolated Barrier with 24 V DC Supply and SIL 2 Certification

Pepperl+Fuchs intrinsic safety barriers limit energy supplied to circuits and protect hazardous areas from excess energy. By limiting energy to safe levels, these circuits prevent ignition of potentially explosive atmospheres.

Beyond explosion protection, isolated barriers provide galvanic isolation to protect measurement and control circuits from signal distortion and dangerous surges. These interface modules also convert, standardize, and split measurement and control signals.

The Pepperl+Fuchs K-System delivers reliable and economical signal transmission between field devices and control systems. From single isolating modules to large-scale system integration, the K-System offers application-oriented solutions for diverse requirements.

• Comprehensive Product Portfolio - Extensive range of intrinsic safety interface modules for various signals and applications
• Power Rail Technology - DIN rail insert that simplifies mounting, reduces wiring costs, and enables easy system expansion
• Power Feed Modules - Built-in fuse protection and collective error messaging via potential-free contacts
• International Safety Standards - SIL ratings available at no extra cost
• Easy Configuration - Simple setup and documentation using PACTware software tool

This signal conditioner provides galvanic isolation between field circuits and control circuits. The device repeats input signals from control systems to drive SMART I/P converters, electrical valves, and positioners located on the field side.

Digital signals are superimposed on analog values and transferred bi-directionally. Current is transferred via DC/DC converter and repeated at output terminals. Open field circuits present high impedance to the control side, enabling alarm condition monitoring by the control system. Integrated test sockets allow connection of HART communicators directly at device terminals.
