PRODUCT DESCRIPTION
PEPPERL & FUCHS 192999 - K-System Intrinsic Safety Barrier, Current Converter
This K-System intrinsic safety barrier provides galvanic isolation and signal conversion for analog current signals originating from hazardous areas. Engineered for process automation, it ensures safe operation by limiting energy to field devices in Ex ia IIC environments while transmitting a proportional 4-20mA signal to the safe area control system. It is designed for DIN rail mounting within industrial control cabinets.
