Schneider TM221CE24R

Schneider Electric TM221CE24R – Product Overview

The Schneider TM221CE24R is a compact and powerful programmable logic controller (PLC) from the Modicon M221 family. Designed to meet the automation needs of small to medium-sized machines, this controller provides an excellent balance between performance, flexibility, and ease of use. It is particularly suitable for OEMs, system integrators, and maintenance professionals who require a reliable solution for machine control and automation.

The controller operates on 100–240V AC supply and comes equipped with 14 digital inputs and 10 relay outputs. It also features integrated Ethernet, serial (RS232/RS485), and USB ports, allowing seamless communication and data exchange across different devices and networks. Its design supports both standalone and networked automation architectures, making it adaptable for a wide range of industrial applications.

Key Features

• Integrated I/O
  The TM221CE24R provides 14 discrete inputs and 10 relay outputs, which are sufficient for many small to mid-range automation tasks. This built-in I/O allows for direct connection to sensors, actuators, switches, and other field devices without the need for additional hardware.

• Communication Interfaces
  The controller comes with several built-in communication ports:

  • Ethernet Port (RJ45) – for Modbus TCP and programming

  • Serial Port (RS232/RS485) – supports Modbus RTU/ASCII protocols

  • USB Mini-B – used for local programming and diagnostics

• Analog Input Capability
  It includes 2 analog inputs (0–10V), useful for connecting analog sensors like temperature probes, pressure transducers, and flow meters.

• Expandable Architecture
  The TM221CE24R supports up to 7 TM3 expansion modules, allowing users to add more I/O points as their system requirements grow. This modularity ensures investment protection and system scalability.

• Programming Environment
  Programmed using EcoStruxure Machine Expert – Basic software (formerly SoMachine Basic), which supports IEC 61131-3 languages including Ladder Diagram (LD), Function Block Diagram (FBD), and Structured Text (ST). This ensures compatibility with industry standards and accelerates development cycles.

• Memory and Performance
  The controller has a generous internal memory allocation (256 KB for application programs), ensuring support for complex logic operations. It offers fast cycle times and reliable execution even in dynamic environments.

• Industrial-Grade Design
  Built to operate in harsh industrial environments, it supports a temperature range of -10°C to +55°C and high humidity conditions (up to 95%, non-condensing). The rugged housing and compliance with international standards make it suitable for global applications.
