ОПИСАНИЕ ПРОДУКТА
PEPPERL & FUCHS 262112 - K-System Intrinsic Safety Barrier - Switch Amplifier
Dual-channel intrinsic safety barrier from the K-System series, engineered for isolating and controlling circuits in hazardous areas. It provides intrinsically safe power and signal conditioning for NAMUR sensors or mechanical contacts, transmitting their status via potential-free relay outputs to safe area control systems. This module ensures compliance with intrinsic safety standards for critical process automation applications.
