Schneider Electric TSXSTZ10 Modicon Premium Bus Expansion Termination Block

Description

The TSXSTZ10 is a dedicated line termination adapter designed for the Schneider Electric Modicon Premium automation network. This module is engineered to terminate high-speed TSXBusX backplane segments, matching the characteristic impedance of the distributed rack system data paths. It ensures precise electrical termination and signal stabilization for multi-rack setups in demanding industrial environments, including power generation, oil and gas, and mining operations. By absorbing residual transmission reflections and maintaining signal integrity, the TSXSTZ10 prevents data packet corruption, network synchronization dropouts, and system faults.

Features

• Passive, high-precision resistor-capacitor (RC) network design.
• Matches 100 Ohm nominal impedance of the TSXBusX communications line.
• Integrated 9-pin male Sub-D connector with locking screws for vibration-resistant, gas-tight connectivity.
• Passive operation requiring no external power supply.
• Heavy internal shielding for EMI protection and continuous grounding path.
• Compact, rugged housing rated for IP20 protection.

Applications

The TSXSTZ10 is essential for any Modicon Premium system utilizing TSXBusX rack extensions. It is typically deployed at the end of a communication segment to ensure the stability of the high-speed expansion bus, particularly in systems spanning multiple racks or long distances where signal reflection could compromise data integrity.

Technical Specifications

Installation Guidelines

• Ensure the system is powered down before installing or removing any bus components.
• The TSXSTZ10 plugs directly into the unused 9-pin female bus extension port on the final TSXRKY extension rack base.
• Secure the module using the integrated locking screws to ensure a gas-tight connection and proper grounding through the rack chassis.
• Avoid routing communication cables near high-voltage lines or sources of significant electromagnetic interference.
• Ensure the environment remains within the specified temperature and humidity ranges to maintain long-term reliability.

FAQ

Does this module require an external power supply?

No, the TSXSTZ10 is a completely passive device that requires 0.0 W of power. It derives its operational grounding path directly through the metallic shielding of the connected rack chassis.

Where should the TSXSTZ10 be installed?

This termination block must be installed on the final TSXRKY extension rack base of a TSXBusX communication segment to properly terminate the bus and prevent signal reflections.
