Honeywell FC-BSN-1608 Safe Namur Sensor Converter

The Honeywell FC-BSN-1608 Safe NAMUR Sensor Converter is an advanced interface module specifically designed for converting NAMUR-type sensor signals into logic-level signals suitable for direct processing by safety systems such as Honeywell Fail Safe Controller (FSC) and Experion PKS architectures.

NAMUR sensors are widely used in critical applications that demand intrinsically safe field wiring and high-integrity signal isolation. The FC-BSN-1608 module is engineered to accept standard NAMUR signals and convert them reliably for safe operation in Safety Integrity Level (SIL) rated systems. This makes it an ideal component for safety-critical industries where functional safety compliance is required, including oil & gas, chemical processing, power generation, and pharmaceuticals.

The module ensures precise signal conditioning, provides fault detection (such as open/short circuits), and is fully certified for use in hazardous zones. It also includes channel-level diagnostics and galvanic isolation, safeguarding both field and control equipment from electrical disturbances.

The FC-BSN-1608 represents an essential part of modern process safety infrastructure, providing dependable, repeatable NAMUR signal interfacing across a range of industrial sectors.
