SCHNEIDER ELECTRIC TSXTLYEX

Schneider Electric Modicon Bus X Terminator Set

Description

The TSXTLYEX is a set of two essential bus terminators designed by Schneider Electric for the Modicon series. These terminators are crucial for maintaining stable and error-free communication on Modbus Plus and Uni-Telway networks. By providing the correct termination impedance at both ends of the bus, they prevent signal reflections that can corrupt data and cause network failures. This set includes two terminators, A and B, to properly outfit a single network segment.

Application

This terminator set is used in industrial automation environments with legacy Schneider Electric PLC systems. It is installed at the physical start and end of a Modbus Plus or Uni-Telway network cable to ensure reliable data transmission, particularly in long cable runs or high-speed applications.

Country of Origin

Made in China.

CO2 Impact

Opting for this pre-owned set of terminators instead of new production avoids the emission of approximately 2.0 kg of CO2, contributing to a more sustainable industrial operation.

FAQ

What networks are these terminators for?

These terminators are specifically designed for Schneider Electric’s legacy Modbus Plus and Uni-Telway networks. They are not suitable for other bus systems like Profibus or CANopen, which have different impedance requirements.

Is this a complete set?

Yes, the TSXTLYEX is sold as a complete set of two terminators, typically labeled A and B. Both must be used, one at each physical end of the network bus cable, for proper termination.

What is the resistance value of these terminators?

While not explicitly printed on the device, standard Modbus Plus terminators have a resistance of 120 ohms to match the characteristic impedance of the specified twisted-pair cabling and ensure signal integrity.
