Schneider Electric TSXSAY1000 Programmable Logic Controller Module

TSXSAY1000 is Schneider Electric’s AS-Interface master module for the Modicon TSX Premium automation family. Acting as the AS-i bus master (Version 2), it enables a Premium PLC to coordinate communication with AS-i slaves—sensors, actuators, and distributed I/O—over the AS‑Interface fieldbus, simplifying wiring and field connections. The module is powered from a 5 V DC supply and typically draws up to 450 mA, and it is offered in Standard and Extended variants as part of Schneider’s AS‑Interface cabling system. In typical installations with a Premium controller such as TSX P57, PCX 57, or PCI 57 hosts, TSXSAY1000 manages addressing and data exchange for up to 31 AS-i devices in standard and extended modes, enabling scalable field networks within the TSX platform. By integrating the TSXSAY1000 into the control cabinet, engineers can streamline connections to field devices while maintaining master‑level control of the AS‑i network and ensuring compatibility with Schneider Electric’s automation ecosystem and supporting software.
