Modular Control, Maximum Flexibility
When your existing PLC controller reaches its limits, the TSX3721101 from Schneider Electric provides a straightforward upgrade path. This modular base controller, part of the TSX Micro 37/22 family, delivers the processing power and connectivity you need to keep your automation lines running efficiently. With its compact 3-slot design and integrated communication ports, the TSX3721101 simplifies system architecture while offering the performance required for demanding applications.
Technical Specifications: Built for Speed and Reliability
The TSX3721101 is engineered to handle both logic and data-intensive tasks. Its processing capabilities are impressive, with Boolean execution times as fast as 0.13 µs (without PCMCIA card) and 0.19 µs (with PCMCIA card). For floating-point arithmetic, the controller achieves 4.5 µs per instruction, ensuring precise calculations for process control. The controller also manages a full application structure, supporting 1 fast task, 1 master task, and up to 16 event tasks, giving you the flexibility to prioritize critical processes.
Memory is another strong suit. The base unit includes 128 Kwords of internal RAM for data storage, expandable to 128 Kwords for program and data when using a PCMCIA card. Additionally, 20 Kwords of internal RAM and 15 Kwords of Flash memory are available for data. This capacity supports complex programs and substantial data logging without external memory modules.
Communication is built-in, with one Modbus RTU port running at 19.2 kbit/s and one serial link (TER/AUX) supporting Uni-Telway at the same speed. These integrated connections reduce the need for additional communication modules, simplifying installation and lowering costs.
Real-World Applications: Solving Downtime Issues
In manufacturing environments, unplanned downtime is the enemy of productivity. The TSX3721101 addresses this by providing robust protection against overload and short-circuits, safeguarding your investment and minimizing interruptions. Its fast processing speed ensures that control loops respond quickly, reducing the risk of process upsets.
Consider a packaging line where precise timing is critical. The TSX3721101’s fast Boolean execution (0.13 µs) ensures that sensor inputs are processed and actuator outputs are triggered without delay, maintaining high throughput. In a water treatment facility, the controller’s support for event tasks allows immediate response to alarm conditions, enhancing system safety and reliability.
Installation and Setup: Simple Integration
Replacing or upgrading your controller does not have to be a complex project. The TSX3721101 fits into existing TSX Micro racks, and its 3-slot configuration provides ample space for I/O modules. The integrated communication ports mean fewer cables and simpler wiring. Before installation, verify that your power supply meets the total useful secondary power requirement of 16 W. Also, ensure that the ambient temperature remains within the operating range of 0 to 60 °C and that relative humidity stays between 5% and 95% (non-condensing).
Maintenance and Reliability: Long-Term Performance
To ensure long-term reliability, periodic inspection of the controller and its connections is recommended. Check for dust accumulation on the enclosure and ensure that ventilation is not obstructed. The controller’s design includes overload and short-circuit protection, which helps prevent damage from electrical faults. Regular monitoring of the real-time clock and battery (if applicable) will help maintain accurate timestamps for data logging. Following the manufacturer’s guidelines for maintenance will extend the life of your TSX3721101 and reduce the total cost of ownership.
Compatibility and Integration: Seamless Connectivity
The TSX3721101 is designed to work within the TSX Micro 37/22 PLC architecture. Its integrated Modbus RTU port allows easy connection to HMIs, SCADA systems, and other Modbus-compatible devices. The Uni-Telway serial link provides an additional communication channel for programming and diagnostics. This compatibility ensures that you can integrate the controller into your existing automation network with minimal effort.
Selection Guide: What to Consider Before You Buy
Before ordering the TSX3721101, confirm that it matches your application requirements. Check the number of I/O points you need and ensure that the 3-slot base can accommodate your modules. Verify that the memory capacity (128 Kwords data, 20 Kwords internal RAM, 15 Kwords Flash) is sufficient for your program size. Also, consider whether you need the PCMCIA card for expanded program memory. For current availability and lifecycle status, contact SpareTechPLC.

Frequently Asked Questions
Can the TSX3721101 be used as a direct replacement for an existing TSX Micro controller?
Yes, the TSX3721101 is part of the TSX Micro 37/22 family and is designed to fit into the same rack systems. However, always verify the firmware version and program compatibility before swapping out an existing unit.
What is the maximum program size I can store on the TSX3721101?
Without a PCMCIA card, the controller provides 128 Kwords of internal RAM for data and 20 Kwords for data. With a PCMCIA card, you can expand the program and data memory to 128 Kwords. This allows for substantial application logic and data storage.
Does the TSX3721101 support real-time clock functionality?
Yes, the TSX3721101 includes a real-time clock, which is essential for time-stamping events, scheduling tasks, and maintaining accurate logs.
What communication protocols are supported by the TSX3721101?
The controller features an integrated Modbus RTU port (19.2 kbit/s) and a serial link (TER/AUX) supporting Uni-Telway at 19.2 kbit/s. These protocols enable easy integration with many industrial devices.
How fast is the TSX3721101 at executing instructions?
Boolean instructions execute in as little as 0.13 µs (without PCMCIA card) or 0.19 µs (with PCMCIA card). Arithmetic REAL floating operations take 4.5 µs per instruction. This speed ensures responsive control in time-critical applications.
