Product Description

The Schneider Electric TSX3721101 is a high-performance modular base controller from the renowned Modicon TSX Micro series. Engineered for compact to mid-sized industrial automation, this PLC (Programmable Logic Controller) offers a versatile platform for machine control, featuring integrated analog capabilities and high-speed counting. Its modular architecture allows for significant I/O expansion, making it an ideal choice for OEMs and plant engineers looking for a balance between a small form factor and powerful processing.

Operating on a standard 24VDC supply, the TSX3721101 is built to withstand industrial power fluctuations with a 10ms power loss tolerance. It supports the UNI-TELWAY communication protocol for seamless integration with HMIs and other Schneider Electric hardware. Whether managing complex logic or high-speed counting at 10 kHz, this French-made controller provides the reliability and precision required for modern manufacturing environments.
