Schneider TM241CE40U

Product Overview

The Schneider TM241CE40U is a compact yet powerful programmable logic controller (PLC) from the Modicon M241 series, designed to deliver high-performance control in a modular, scalable format. Built for industrial automation environments, it combines a rich set of onboard inputs and outputs with advanced processing capabilities and integrated communication ports.

This model features 24 digital inputs (8 of which support high-speed counting) and 16 transistor outputs (including 4 high-speed outputs capable of PWM, PTO, or frequency generation), for a total of 40 discrete I/O points. It operates on a 24 V DC power supply and is housed in a DIN-rail mountable enclosure with IP20 protection.

In addition to its local I/O, the TM241CE40U supports multiple expansion modules, enabling the system to grow alongside application needs. It comes with built-in Ethernet, USB, and dual serial ports for seamless integration into modern machine architectures. With strong data handling capabilities, including internal memory and an SD card slot, it supports recipe management, data logging, and firmware upgrades directly in the field.

Its rugged design allows operation in challenging industrial conditions, with a typical temperature range from –10 °C to +55 °C, and it complies with major industrial certifications, ensuring reliability and safety in long-term deployments.
