PHOENIX Passive module 2321842 FLKM-2KS50/BFI/SPT/CS/C-L

The PHOENIX CONTACT Passive Module 2321842 (FLKM-2KS50/BFI/SPT/CS/C-L) represents the pinnacle of innovation in industrial connectivity. This pre-assembled interface cable is engineered for mission-critical fieldbus and Ethernet-based automation systems. It combines advanced SPT (Smart Plug & Technology) for intelligent diagnostics with the secure C-L (Chirp-Lock) mechanical latching system and a robust BFI (Fieldbus Interface) connector. Designed for PROFINET, PROFIBUS, and other fieldbus applications, this module ensures maximum network integrity, operational reliability, and effortless maintenance in the most demanding industrial environments.

Key Features & Benefits

• Intelligent Diagnostics with SPT: Smart Plug & Technology (SPT) enables electronic identification and channel-specific diagnostics. This provides precise error messaging in the controller (e.g., "Module Missing"), drastically reducing mean time to repair (MTTR) and enabling predictive maintenance strategies.

• Secure Tool-Less Locking (C-L): The Chirp-Lock (C-L) mechanism provides an audible click for confirmed mating, a vibration-proof connection, and tool-less insertion and removal. This enhances reliability in high-vibration environments and speeds up maintenance procedures.

• Optimized Fieldbus Performance (BFI): The BFI (Fieldbus Interface) connector is specifically designed for PHOENIX CONTACT's fieldbus components, ensuring perfect impedance matching and a reliable connection for high-speed data communication on networks like PROFINET.

• Superior Signal Integrity (2KS): The cable features a twisted pair design with an overall braided shield, offering maximum protection against electromagnetic interference (EMI) and guaranteeing stable, error-free data transmission.

• Pre-assembled Reliability: Factory-assembled connectors guarantee perfect termination, eliminate installation errors, and provide a plug-and-play solution that ensures network integrity from the start.

Technical Specifications

Applications

This intelligent fieldbus module is designed for building highly reliable and easily maintainable network infrastructures in:

• PROFINET and PROFIBUS Networks: Connecting controllers to the first node in a remote I/O drop or between segments in a daisy-chain topology.

• High-Vibration Environments: Robotics, automotive assembly, material handling, and processing plants where the secure C-L latch is critical.

• Mission-Critical Systems: Applications where network downtime is costly, and advanced SPT diagnostics are essential for rapid fault identification.

• Industry 4.0 / IIoT Implementations: Systems that require component-level identification, diagnostics, and data for smart manufacturing and digital twin applications.

Compatibility & Integration Notes

• This module requires a compatible SPT and C-L enabled PHOENIX CONTACT fieldbus coupler or controller (e.g., from the Inline family) to utilize its full diagnostic and locking features.

• The BFI connector is designed for specific PHOENIX CONTACT fieldbus components.

• The SPT technology requires configuration in the controller software to enable advanced diagnostic reporting.
