TM221C24R Controller 24V DC 14 Inputs 10 Outputs Schneider

TM221C24R Modicon M221 Compact Logic Controller

Product Introduction

The Schneider Electric Modicon TM221C24R offers a powerful yet space-saving control solution for your automation needs. This controller belongs to the well-established Modicon M221 series, known for its balance of performance and affordability. It integrates 14 digital inputs and 10 relay outputs into a single compact unit. Furthermore, it includes 2 analog inputs for reading 0-10V signals, expanding its application range. This makes the TM221C24R an excellent choice for OEMs and panel builders.

Technical Specifications

The TM221C24R operates on a 24 V DC power supply, which is standard in many industrial environments. Its digital inputs accept a variety of sensors and switches. The 10 relay outputs are suitable for driving contactors, solenoids, and indicator lights. Additionally, the 2 analog inputs allow for process value monitoring, such as pressure or temperature sensors.

At the heart of this controller lies a 32-bit processor that executes instructions at a speed of 22 ns per instruction. This ensures rapid response times for time-critical applications. For program storage, the TM221C24R provides 256 kB of memory. It also includes 64 kB of retention memory to preserve important data during power cycles. Consequently, your application data remains safe and accessible.

Expansion and Connectivity

This Modicon controller supports expansion through additional I/O modules. You can easily add more digital or analog points as your system grows. A built-in real-time clock is also included, enabling time-stamped events and scheduled tasks. This feature is particularly useful for batch processes and data logging. Therefore, the TM221C24R offers flexibility that adapts to evolving project requirements.

Mechanical and Environmental Parameters

The TM221C24R is designed for reliable operation across a wide range of conditions. Its operating temperature spans from -10°C to 55°C, covering most indoor industrial settings. The unit is rated for DIN rail mounting, which simplifies installation in standard control cabinets. With dimensions of 130 mm in length and 95 mm in width, it occupies minimal panel space. This compact footprint makes it a practical choice for space-constrained applications.

Installation Guidelines

Proper installation ensures optimal performance and longevity for the TM221C24R. Begin by securely clipping the unit onto a standard DIN rail inside your control cabinet. Next, connect the 24 V DC power supply to the designated terminals, observing correct polarity. For the digital inputs, wire your sensors or switches to the appropriate input terminals. Similarly, connect your actuators to the relay output terminals, respecting the maximum current ratings. Use twisted-pair cables for the analog inputs to minimize electrical noise. Finally, ground the controller properly to protect against interference.
