PEPPERL & FUCHS 088195 - K-System Switch Amplifier Safety Relay
PEPPERL & FUCHS 088195 is a K-System single-channel switch amplifier engineered for intrinsic safety applications in hazardous areas. It provides galvanic isolation between the hazardous and safe areas, conditioning signals from NAMUR proximity sensors or potential-free contacts and driving a relay output for control system integration. This module is designed for reliable operation in safety instrumented systems (SIS) up to SIL 2, ensuring process integrity and personnel safety.
