The TSX3721001 model from Schneider Electric's TSX Micro PLCs series operates as a controller module with a dedicated real-time clock. Its memory architecture is robust, consisting of internal RAM capable of 20 Kwords for data management, along with capacity expansions available when utilizing a PCMCIA card, allowing for 128 Kwords of program and data storage. There is also an additional 15 Kwords in flash memory for storing information.

Object areas are designed to accommodate up to 256 %Mi, with 1 %MWi allocated for internal data storage and 128 %KWi reserved for constant values. Execution times for processing instructions are efficient, offering 5.88 milliseconds for 100% Boolean operations without a PCMCIA card while supporting a reduced 0.266 milliseconds when using one, depending on the task's complexity.

The application structure consists of one fast task, one master task, and up to 16 event tasks, allowing versatile programming capabilities. The master task executes with a system overhead of 1.6 milliseconds, ensuring rapid response and reliability during operation. The device has an IP30 rating and complies with multiple electromagnetic compatibility standards to protect against interference and electrical noise.

Operating under a primary voltage range of 100 to 240 V AC, the controller draws an input current of only 2 mA while sustaining a maximum output current of 0.5 A. It is designed to withstand microbreaks of less than 20 milliseconds, improving its resilience. The unit features three integration slots, supporting a serial link with Uni-Telway at 19.2 kbit/s and Modbus RTU at the same rate, facilitating effective communication in automation systems while enhancing connectivity options.
