PHOENIX Passive module 2321826 FLKM-2KS40/SPT/CS

The PHOENIX CONTACT Passive Module 2321826 (FLKM-2KS40/SPT/CS) is an intelligent, pre-assembled interface cable designed for modern industrial automation systems. It seamlessly bridges the gap between field devices and modular I/O stations by combining robust physical connectivity with advanced digital diagnostics through SPT (Smart Plug & Technology). This module transforms a simple passive connection into a smart, diagnosable system component, providing unprecedented visibility into your control system's health and status.

Key Features & Benefits

• Intelligent Diagnostics with SPT: Smart Plug & Technology (SPT) enables electronic identification of the cable module at the controller level. This allows for precise, channel-specific error messaging (e.g., "Module Missing"), drastically reducing troubleshooting time and enabling predictive maintenance strategies.

• Pre-assembled Reliability: Factory-terminated connectors guarantee perfect contact integrity, eliminate on-site crimping errors, and provide a vibration-proof connection that ensures long-term signal integrity.

• Superior Signal Integrity (2KS): Features a twisted pair design with an overall braided shield, offering maximum protection against electromagnetic interference (EMI) for both sensitive analog and high-speed digital signals.

• Plug-and-Play Installation: The ready-to-use design allows for quick and error-free integration into automation systems, significantly reducing commissioning time and costs.

• Future-Proof Design: As an essential component of Industry 4.0 and IIoT-ready systems, it provides the foundational intelligence for digital twins and smart manufacturing initiatives.

Technical Specifications

Applications

This intelligent interface cable is designed for building reliable and easily diagnosable control systems in:

• SPT-enabled Modular I/O Systems: Connecting fieldbus couplers to I/O modules and interlinking modules within a PHOENIX CONTACT Inline station.

• High-Availability Automation: Applications where minimizing downtime is critical and advanced diagnostics are essential for rapid maintenance.

• Process Control Systems: Where signal integrity is paramount for analog measurement and control loops.

• Industry 4.0 / IIoT Implementations: Systems that require component-level identification and diagnostics for predictive maintenance and data analytics.

• Automated Assembly and Packaging Lines: Where quick identification of connection failures improves overall equipment effectiveness (OEE).

Compatibility & Integration Notes

• This module requires a compatible SPT-enabled PHOENIX CONTACT I/O system (e.g., the Inline family with SPT) to utilize its diagnostic features.

• The system-side connector is designed to plug directly into specific SPT-enabled I/O module ports.

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