TSXPBSCA100 Schneider Electric Modicon Quantum Profibus DP Cable 100m

Product Overview

The TSXPBSCA100 (TSXPBSCA100) is a premium-grade Profibus DP communication cable engineered for high-speed data transmission within the Schneider Electric Modicon Quantum and Premium automation platforms. This 100 m (328 ft) bulk cable reel is specifically designed to facilitate robust connectivity between Profibus master/slave modules and field devices in distributed I/O architectures. Utilized extensively in large-scale industrial sectors such as water wastewater treatment, automotive assembly, and chemical processing, the TSXPBSCA100 ensures low-latency communication over long distances. Its industrial-strength shielding is critical for maintaining signal integrity in environments saturated with electromagnetic interference (EMI), effectively preventing data packet loss and minimizing network-related system downtime.

Technical Configuration

The TSXPBSCA100 is a specialized RS-485 based twin-axial cable optimized for the Profibus DP (Decentralized Periphery) protocol. The internal architecture features high-purity copper conductors protected by a high-density braided shield and foil wrap, providing dual-layer protection against high-frequency noise and electrical transients. The outer jacket is composed of a durable, flame-retardant compound capable of withstanding the rigors of industrial cable trays and conduits. This cable is designed for use with standard 9-pin D-Sub Profibus connectors, supporting transmission speeds up to 12 Mbps. Its 100 m length provides the flexibility needed for expansive plant layouts, allowing for the strategic positioning of remote I/O drops without the need for frequent repeaters.

Technical Specifications

Technical FAQs

Can the TSXPBSCA100 cable be used for both Profibus DP and Profibus PA?

This cable is specifically optimized for Profibus DP (RS-485). While the physical layer of Profibus PA is different (Manchester Bus Powered), the TSXPBSCA100 is the standard for high-speed DP communication between PLCs and devices like variable speed drives or remote I/O.

Is it necessary to use specific connectors with this 100 m reel?

Yes, for industrial reliability, it is recommended to use Schneider Electric 490NAE91102 or equivalent Profibus connectors. These connectors provide the necessary termination resistors required at the physical ends of the network segment.

What is the maximum segment length supported by this cable at 1.5 Mbps?

According to Profibus standards, a single segment using this type of high-quality cable can reach up to 200 m at 1.5 Mbps. For the full 12 Mbps speed, the segment length should generally not exceed 100 m without a repeater.

Engineering & Installation Guide

• Minimum Bend Radius: During installation, strictly observe a minimum bend radius of at least 75 mm. Kinking or over-bending the TSXPBSCA100 can deform the internal dielectric and shielding geometry, leading to impedance mismatches and signal reflections that cause intermittent bus errors.

• Shielding Continuity: When stripping the cable for connector assembly, ensure the braided shield makes 360-degree contact with the metal housing of the Profibus connector. This ensures a continuous path to ground for induced noise, which is vital for the 12 Mbps high-speed data rates.

• Separation from Power Cabling: To avoid inductive coupling, maintain a minimum clearance of 20 cm between the TSXPBSCA100 and AC power cables (above 230V). If the communication cable must cross a power cable, ensure it does so at a 90-degree angle.

• Termination Check: Always verify that the termination switches on the connectors at the first and last physical nodes of the 100 m segment are set to the "ON" position. Intermediate nodes must have the termination switch set to "OFF" to prevent signal attenuation.
