Compact Processing Core for Modicon Premium Automation
The Schneider TSX3722001 serves as a modular base controller within the Modicon Premium family, delivering robust processing power for mid-sized automation tasks. This controller features a built-in 32-bit processor running at 40 MHz, providing efficient execution of logic and motion control programs. Its base unit measures 185 mm in height, 65 mm in width, and 130 mm in depth, occupying minimal backplane space. The total weight reaches approximately 0.9 kg, which facilitates straightforward mounting in standard control cabinets.
This controller integrates 128 KB of user memory and 384 KB of system RAM, supporting complex application code and data storage. The following table details the complete technical specifications for this modular controller:

Memory Architecture and Data Retention
The controller utilizes a supercapacitor-based energy storage system to preserve critical data during power interruptions. This backup mechanism retains user programs and application variables for up to 72 hours without external power. Such robust retention protects ongoing processes from losing valuable production data. The system RAM operates alongside the user memory, ensuring smooth multitasking for time-critical control loops.
Communication Capabilities and I/O Integration
A dedicated Modbus communication port enables seamless connectivity with HMI panels, drives, and remote I/O stations. An additional RS-485 port supports multi-drop networking for distributed control architectures. The base unit includes 28 integrated digital I/O points, reducing the need for extra modules in smaller applications. Engineers can therefore deploy this controller as either a standalone solution or as part of a larger Premium system.
Environmental Resilience and Installation Flexibility
Operating temperatures from 0°C to +60°C cover a wide range of industrial environments without derating performance. The storage temperature range from -25°C to +70°C ensures product integrity during transport or seasonal storage. Panel mounting or DIN-rail installation offers flexible integration into new or existing control cabinets. The lightweight design also simplifies maintenance procedures and system upgrades over time.
