PEPPERL & FUCHS 233261 - K-System Intrinsic Safety Barrier, Repeater Power Supply with Control Input
The PEPPERL & FUCHS 233261 is a K-System intrinsic safety barrier, functioning as a repeater power supply with an integrated control input. It provides galvanic isolation and power to 2-wire transmitters located in hazardous areas, transmitting their 4-20mA analog signals to the safe area. Simultaneously, it enables digital control signals from the safe area to actuate functions within the hazardous zone, ensuring intrinsic safety compliance for critical process automation applications.
