Product Overview
When your industrial automation system demands reliable and flexible control, the Schneider TSX3721101 Modular Base Controller delivers. This controller is part of the TSX Micro 37 21/22 PLC family and provides a robust foundation for your automation tasks. With 3 slots for expansion modules, it offers scalability to meet your application needs.
Technical Specifications Breakdown
The TSX3721101 integrates essential communication and processing features. It includes one Modbus RTU serial link operating at 19.2 kbit/s and one serial link (TER/AUX) for Uni-Telway at 19.2 kbit/s. The built-in real-time clock ensures accurate time-stamping for events and data logging.
Memory capabilities are comprehensive: internal RAM of 128 Kwords for data storage, 20 Kwords for data, and 15 Kwords of Flash memory. With a PCMCIA card, you can expand program and data memory to 128 Kwords. The controller supports up to 256 %Mi internal words, 1 %MWi internal words, and 128 %KWi constant words.
Execution speed is impressive: Boolean operations take 0.13 µs without a PCMCIA card and 0.19 µs with one. Arithmetic REAL floating operations complete in 4.5 µs regardless of card presence. The application structure includes 1 fast task, 1 master task, and 16 event tasks, with a system overhead of 1.6 ms for the master task.
Protection features include overload and short-circuit protection, with total useful secondary power of 16 W. Electromagnetic compatibility meets IEC 61131-2 and other standards, ensuring reliable operation in industrial environments.
Industry Applications
In manufacturing lines, the TSX3721101 excels at controlling conveyor systems, sorting stations, and packaging machinery. Its Modbus RTU communication enables seamless integration with sensors, actuators, and HMIs. The real-time clock supports time-based scheduling and batch tracking.
For building automation, this controller manages HVAC systems, lighting controls, and access points. The multiple task structure allows simultaneous handling of fast processes and slower monitoring tasks, improving overall system efficiency.
Installation & Setup Guidance
Mount the TSX3721101 on a DIN rail or panel using the provided slots. Ensure adequate ventilation around the unit, as operating temperature ranges from 0 to 60 °C. Connect the Modbus RTU link using shielded twisted-pair cable for reliable communication. The serial TER/AUX port uses Uni-Telway protocol at 19.2 kbit/s. Configure the real-time clock during initial setup to enable accurate time-stamping.
Maintenance & Reliability
Regularly inspect the controller for dust accumulation and ensure ambient temperature stays within 0 to 60 °C. The unit operates at altitudes up to 2000 m and relative humidity of 5 to 95% without condensation. Check connections periodically to maintain signal integrity. With overload and short-circuit protection, the TSX3721101 minimizes downtime and extends service life.
Compatibility & Integration
The TSX3721101 integrates with TSX Micro 37 21/22 PLC systems and supports Modbus RTU and Uni-Telway protocols. It works with Schneider Electric programming software and can interface with various I/O modules, drives, and HMIs. The PCMCIA card slot allows memory expansion for larger applications.
Selection Guide & Purchasing Advice
Before purchasing, verify that your system requires a TSX Micro base controller with 3 slots and Modbus RTU communication. Confirm compatibility with existing I/O modules and power supply.
