Product Overview
When your legacy PLC controller lacks memory or real-time clock capabilities, the Schneider TSX3721001 provides an upgrade path with an integrated real-time clock and expanded memory. This controller module from the Modicon TSX Micro automation platform is designed for overload protection and short-circuit protection, ensuring reliable operation in demanding industrial environments.
Technical Specifications Breakdown
The Schneider TSX3721001 features a flexible memory architecture: internal RAM with 20 Kwords for data, internal RAM (with PCMCIA card) offering 128 Kwords for program and data, an additional 128 Kwords internal RAM for data storage, and flash memory with 15 Kwords for data. Execution times are efficient—5.88 ms for 100% Boolean without a PCMCIA card and 0.266 ms for mixed Boolean/numerical with a PCMCIA card. The application structure supports 1 fast task, 1 master task, and up to 16 event tasks, with a master task system overhead of 1.6 ms.
Key electrical specs include a primary voltage of 100-240 V AC (90-264 V AC), input current of 2 mA (<60 A inrush), output current of 0.5 A, and total useful secondary power of 16 W. The unit has 3 slots and integrated connection types: 1 serial link (TER/AUX) Uni-Telway at 19.2 kbit/s and 1 Modbus RTU at 19.2 kbit/s.
Industry Applications
The Schneider TSX3721001 is ideal for upgrading older TSX Micro PLC systems in manufacturing lines, process control, and building automation. Its real-time clock enables time-stamped data logging for quality tracking. The robust overload and short-circuit protection safeguard motors and actuators, reducing downtime. For example, in a packaging machine upgrade, the TSX3721001 replaces legacy controllers while maintaining communication via Modbus RTU with existing HMI and drives.
Compatibility & Integration
The Schneider TSX3721001 seamlessly integrates with the Modicon TSX Micro platform. Its dual communication ports—Uni-Telway and Modbus RTU—allow connection to I/O modules, remote terminals, and supervisory systems. The PCMCIA slot supports memory expansion for complex programs. When replacing older TSX Micro controllers, this module ensures backward compatibility with existing racks and power supplies.
Selection Guide & Purchasing Advice
Before purchasing the Schneider TSX3721001, verify your system's voltage compatibility (100-240 V AC) and confirm the required number of slots (3). Ensure you have a compatible PCMCIA card if planning to expand memory. For a reliable supply of genuine automation parts, consider UBEST Automation (ubest101).
