Schneider Electric TSX3722101 Overview

The TSX3722101 is a modular base controller, which is a type of CPU (Central Processing Unit) produced by Schneider Electric as part of their Modicon TSX Micro automation platform. This controller has a primary voltage of 24 VDC and can handle input currents ranging from 2mA to 60A. These products are manufactured in France and are designed for Material handling, packaging, and textile machines usage. They come with a 2-year warranty from MRO Electric. We also carry CPUs from other manufacturers such as Modicon and ABB.


The TSX3722101 is designed to withstand various electromagnetic disturbances, as it meets the requirements for Electrostatic Discharge (ESD) IEC 1000-4-2 level 3, Electromagnetic Field Immunity Test IEC 1000-4-3 level 3, Resistance to Fast Transient IEC 1000-4-4 level 3, Immunity to Impulse Waves IEC 1000-4-5, Damped Oscillatory Wave IEC 1000-4-12, and Immunity to Electromagnetic Interference (EMI) IEC 61131-2.

The modular base controller has three slots and supports up to eight analog inputs and one analog output with a range of 0 to 10 volts. It also has a discrete incremental counter and an integrated connection type consisting of one serial link (TER/AUX) Uni-Telway 19.2 kbit/s and one Modbus Modbus RTU 19.2 kbit/s.


The TSX3722101 has a Real-Time Clock (RTC) and an internal RAM of 20 Kwords for data storage. In addition, it has an internal RAM (with PCMCIA card) of 128 Kwords for program and data storage and 128 Kwords for data storage. It also has a flash memory of 15 Kwords for data storage.

The maximum size of object areas for the controller is 256 %Mi, 1 %MWi internal words, and 128 %KWi constant words. The execution time for one thousand instructions is 5.88 seconds for 100 % Boolean without a PCMCIA card, 4 seconds for 100 % Boolean with a PCMCIA card, and 0.266 seconds for 65 % Boolean and 35 % numerical with a PCMCIA card.


The application structure for the controller includes one fast task, one master task, and sixteen event tasks. The system overhead for the master task is 2.3 milliseconds.

The TSX3722101 is protected against overload and short circuits. It also has a total useful secondary power of 16 watts.

The TSX3722101 modular base controller is a versatile and reliable CPU designed to support a wide range of automation applications. Its compact size and modular design make it an ideal choice for applications with limited space, and its ability to handle up to eight analog inputs and one analog output provides precise control over analog signals.


The TSX3722101's resistance to electromagnetic disturbances, such as EMI and electrostatic discharge, ensures reliable performance in harsh environments, where electrical interference is prevalent. The controller's protection against overload and short circuits also ensures safe and reliable operation, protecting the system from damage and failure.

In summary, the Schneider Electric TSX3722101 modular base controller is a reliable and versatile CPU that is suitable for a wide range of automation applications. Its compact size, precise analog control, and resistance to electromagnetic disturbances make it ideal for use in harsh environments, where reliable and accurate performance is critical. Additionally, its user-friendly interface and low system overhead make it an ideal choice for applications that require high-speed processing and precise control.
