PEPPERL+FUCHS Safety Barrier KFD0-SD2-EX1.1045

This isolated barrier is designed for intrinsic safety applications, providing reliable signal transmission in hazardous environments.

• Drives SMART I/P converters in hazardous areas
• Controls electrical valves and positioners
• Bi-directional transfer of digital signals superimposed on analog values

• Current transferred across DC/DC converter repeated at terminals 1 and 2
• Terminals 2 and 3 for applications without short circuit detection
• High impedance to control side during open or short field circuits
• Internal resistance option for low HART communication resistance
• Integrated test sockets for HART communicators
• Fault signaling via LEDs and separate collective error message output

Open or short field circuits present high impedance to the control side, enabling alarm condition monitoring by the control system.
