Product Description

The P0926AH is a high-precision optical networking module for the Foxboro I/A Series Distributed Control System. It serves as a dual-purpose fiber optic splitter and combiner, enabling redundant fiber topologies and extending Fieldbus network reach without signal degradation.

By converting a single optical input into multiple outputs—or consolidating multiple signals into one—the P0926AH maintains low insertion loss and preserves the inherent EMI immunity of fiber optic communications. Its rugged industrial housing supports reliable operation in control room and marshalling environments.

Technical Specifications

Application

• Network Redundancy: Creates dual-path communication links to maintain DCS connectivity if a fiber segment fails.

• Star Topology Implementation: Distributes control signals from a central processor to multiple remote Fieldbus hubs.

• Long-Distance Signal Expansion: Bridges communication between plant buildings where copper cabling is prone to ground loops or lightning.

FAQ

Does the P0926AH require external power?
No. It is a passive optical module and does not require electrical power to split or combine signals.

Can it be used with single-mode or multi-mode fiber?
It is typically optimized for multi-mode fiber installations common in industrial DCS environments. Verify your cable plant specifications before deployment.
