Product Description

The PFI25-8DN safety barrier is an intrinsically safe isolator designed for robust explosion protection in hazardous industrial environments such as oil & gas, chemical processing, and pharmaceutical sectors. It features 8 isolated input channels and 8 corresponding output channels, enabling secure signal transmission between field devices and control systems. The PFI25-8DN isolator supports universal voltage operation (18-32V DC) and functions reliably across temperatures from -20°C to +60°C. With galvanic isolation up to 2.5kV, it ensures compliance with ATEX/IECEx standards while eliminating ground loops. Key advantages include high noise immunity, low power consumption, and DIN-rail mounting compatibility. Though compact (22.5mm width), it lacks integrated display or configuration interfaces, requiring external tools for parameter adjustments. Its explosion-proof design reliably prevents ignition risks in Zone 0/1/2 areas by limiting energy to intrinsically safe levels.
