Schneider Electric / Telemecanique AS-i Bus Terminator TSXTLYEX

Description

The TSXTLYEX is a passive bus terminator for AS-i (Actuator Sensor Interface) networks, manufactured by Schneider Electric under the Telemecanique brand. This component is essential for maintaining signal integrity within an AS-i bus line. By terminating the end of the cable, it prevents signal reflections that can cause communication errors and system instability. Its compact form factor and standard DB9 connector allow for easy integration into existing setups.

FAQ

An AS-i bus terminator is a passive electronic component placed at both physical ends of the main bus cable. It provides a resistance that matches the cable's characteristic impedance, which absorbs the signal energy. This prevents the signal from reflecting back down the cable, which would otherwise cause interference and data corruption.

Yes, the TSXTLYEX is a passive terminator and is compatible with all standard AS-i specifications, including AS-i 2.0, 2.1, and 3.0, as the underlying physical layer requirements for termination have remained consistent.

Installation is straightforward. The TSXTLYEX features a DB9 male connector. It should be connected to a corresponding DB9 female port located at the very end of your AS-i bus segment, typically on the last device or a dedicated connection box.
