Schneider Electric TSXPBSCA400 Modicon Quantum Profibus DP Connection Cable

Product Overview

The TSXPBSCA400 (TSX-PBS-CA400) is a high-performance Profibus DP connection cable engineered for the Modicon Quantum automation platform. Spanning a total length of 400 meters, this specialized communication medium is designed to facilitate seamless data exchange between PLC processors and remote I/O stations in demanding industrial environments such as oil refineries, power generation plants, and large-scale mining operations. Given its Phase-Out status, securing this original Schneider Electric component is critical for maintaining legacy infrastructure integrity, preventing costly downtime, and ensuring the deterministic performance required for mission-critical control loops.

Technical Configuration

As a dedicated Profibus DP (Decentralized Periphery) physical layer component, this cable features optimized impedance and shielding characteristics to mitigate electromagnetic interference (EMI) over long-distance runs. The 400-meter bulk reel allows for custom length termination or extensive trunk line deployment without the need for additional repeaters in many standard RS-485 network topologies. It is fully compliant with the Modicon Quantum architecture, supporting high-speed cyclic data exchange and diagnostics across the Profibus fieldbus network.

Technical Specifications

Technical FAQs

Is the TSXPBSCA400 compatible with other Modicon series?

While specifically categorized under the Modicon Quantum range, this cable follows standard Profibus DP physical layer specifications and can be utilized with Modicon M580 or M340 systems provided the appropriate Profibus communication modules and connectors are employed.

How does the Phase-Out status affect future maintenance?

As this product is in the Phase-Out phase, Schneider Electric may limit new production. It is highly recommended to maintain onsite spares to ensure immediate recovery during cable damage scenarios, as lead times for legacy accessories typically increase over time.

What are the grounding requirements for a 400-meter run?

To prevent ground loops while maintaining EMI protection, the cable shield should be integrated via 360-degree contact at the connector level. In extended runs, ensure that the potential equalization between different plant areas is within the specified limits of the Profibus standard.

Engineering & Installation Guide

• Minimum Bend Radius: During installation, maintain a minimum bend radius of at least 15 times the outer diameter of the cable. Excessive kinking can alter the internal geometry of the twisted pair, leading to signal reflection and intermittent "Bus Heavy" errors in the PLC diagnostics.

• Separation from Power Lines: To maintain signal integrity, route this cable in separate conduits from high-voltage motor leads or VFD outputs. A minimum clearance of 20 cm is recommended in parallel runs to prevent inductive coupling.

• Environmental Protection: Although designed for industrial use, if the cable is routed through areas with high chemical exposure or standing water, it must be protected by liquid-tight flexible conduits. Ensure all Profibus connectors are tightened to the specified torque to maintain IP-rated seals at the module interface.
