Honeywell 8937-HN2 Fiber Optic Extender Module

Product Description

The 8937-HN2 Fiber Optic Extender Module from Honeywell is designed to extend high-speed data communication over long distances within distributed control system architectures. It serves as a reliable optical interface for Experion PKS and Series 8 I/O installations, ensuring stable signal transmission in electrically noisy and environmentally demanding industrial locations.

By converting electrical signals into optical data streams, this module significantly reduces susceptibility to electromagnetic interference while maintaining deterministic communication performance across remote control and I/O segments.

Key Functional Characteristics

The 8937-HN2 supports high-bandwidth fiber communication suitable for modern control networks requiring both speed and reliability. Its industrial-grade construction allows continuous operation across a wide temperature range, making it appropriate for use in power generation, process industries, and large-scale automation systems.

The module is engineered for seamless compatibility with Honeywell Experion PKS architectures, enabling straightforward integration without additional protocol converters or external signal conditioning hardware.
