Schneider TSXCTY2A | PLC High-Speed Counter Module for Automation

Product Description

The Schneider TSXCTY2A is a high-speed counter/timer module from the Modicon TSX Series 7 PLC family. It is engineered to handle real-time counting and timing operations independently from the PLC CPU, ensuring precise measurement and control in fast industrial processes.

This module provides two independent channels capable of high-speed counting up to 20 kHz per channel. It supports versatile counting modes including up/down counting, frequency measurement, and event counting. By offloading these tasks from the PLC CPU, the TSXCTY2A enhances overall system performance and reliability.

Ideal for machine automation, packaging, material handling, and process industries, the module delivers robust performance with galvanic isolation, LED diagnostics, and flexible configuration via Schneider’s PL7 software. Although it is a legacy product, it remains widely used in many existing TSX Series 7 installations.
