Schneider TM200CE24T Logic Controller 24 I/O Transistor Source

Product Introduction

The TM200CE24T controller belongs to the versatile Modicon M200 family. It is designed for small to medium automation systems that require reliable logic handling and communication. This model provides 24 discrete I/O channels, including fast and high-speed inputs, as well as transistor outputs. Its integrated Ethernet port allows seamless connection to Modbus TCP/IP networks. Furthermore, the controller supports expansion modules for extra I/O capacity. Many users choose the TM200CE24T for its balance of performance and compact size. The unit operates on a 24 V DC supply and delivers robust output current up to 0.5 A per channel.

Technical Specifications

The TM200CE24T integrates 14 discrete inputs and 10 discrete outputs. Among the inputs, four are fast inputs (I2 to I5), while four others serve as high-speed inputs (I0, I1, I6, I7). The remaining six inputs are regular type. For outputs, Q0 and Q1 are fast transistor outputs that support PLS, PWM, and PTO modes up to 100 kHz. The other eight outputs (Q2 to Q9) are standard transistor type. Additionally, the supply voltage range is 20.4 to 28.8 V DC, with nominal power consumption at 16 W. The input logic is compatible with both sink and source configurations, conforming to EN/IEC 61131-2 standards.

Output and Input Performance

Specifically, the output frequency on fast channels reaches 100 kHz, making the TM200CE24T suitable for pulse train positioning or PWM regulation. The maximum current per common output is 2 A for COM 0 and 3 A for COM 1. Meanwhile, the response time for standard outputs is 1 ms for both turn-on and turn-off. High-speed inputs react within 5 µs, ensuring precise signal capture. For regular inputs, the response time is 35 µs on and 100 µs off. The controller also includes configurable filtering times of 0 ms, 3 ms, or 12 ms to adapt to different noise environments.

Communication and Connectivity

This model features three main communication ports. First, a non-isolated RS485 serial link is available on a terminal block. Second, a non-isolated serial port supports both RS232 and RS485 interfaces. Third, an integrated Ethernet port with an RJ45 connector supports 10/100BASE-T and Modbus TCP/IP client/server protocols. Besides this, a USB mini B port allows direct programming via SoMachine-Network. The transmission rate for Ethernet reaches 10/100 Mbit/s over 100 meters. Consequently, the TM200CE24T integrates easily into modern industrial networks.

Memory, Battery, and Real-Time Clock

The internal flash memory provides 512 bytes for program backup. Additionally, an optional 32 GB micro SD card extends data storage capacity. A BR2032 lithium battery maintains the real-time clock and user data for up to 5 years at 25 °C. The backup time during power loss is approximately 3 years at the same temperature. Furthermore, the clock drift is less than 90 seconds per month, ensuring accurate time-stamping for events and logs.

Expansion and Positioning Capabilities

The TM200CE24T supports up to four I/O expansion modules. For relay outputs, the system can handle up to 64 discrete outputs. For transistor outputs, the total can reach 138 points. Moreover, the controller includes an adjustable PID regulator capable of running up to 14 simultaneous loops. The built-in positioning functions cover PWM/PLS modes on two channels at 100 kHz. For high-speed counting, the fast inputs support quadrature (x1, x2, x4), Pulse/Direction, Single phase, and CW/CCW signal types. This flexibility makes the TM200CE24T ideal for motion control and packaging machinery.

Electrical Protection and Insulation

Protection features are essential in industrial environments. Therefore, the transistor outputs include overload and short-circuit protection at 2 A, with an automatic reset time of 1 second. The maximum tungsten load is 12 W for both standard and fast outputs. Insulation between input groups, output groups, and the internal logic is rated at 500 V AC. Between the power supply and internal logic, the insulation level is 500 V DC. These characteristics ensure safe operation under demanding conditions.

Mechanical and Environmental Ratings

The TM200CE24T measures 130 mm wide, 90 mm high, and 70 mm deep. It weighs only 0.424 kg net, making it easy to mount on a DIN rail or panel. The IP20 protection rating applies when the protective cover is in place. Operating temperature ranges from 0 °C to 55 °C in horizontal installation. Storage temperature spans -25 °C to 70 °C. Meanwhile, relative humidity can reach up to 95% without condensation. Vibration resistance is rated at 3.5 mm from 5 to 8.4 Hz on a rail, and shock resistance up to 15 gn for 11 ms.

Installation and Wiring Guidance

Mount the controller on a standard TH35-15 or TH35-7.5 rail according to IEC 60715. Alternatively, you can fix it to a panel using an optional kit. For inputs, use unshielded cables up to 50 meters. For high-speed or fast inputs, shielded cables are recommended and limited to 10 meters. Output wiring can run unshielded up to 150 meters. All connections use removable screw terminal blocks for easy maintenance. The power supply connects via a 3-terminal block, while the serial link uses a 4-terminal connector.

Frequently Asked Questions (FAQ)

1. Can the TM200CE24T replace an older Modicon M200 model with fewer I/Os?
Yes, the TM200CE24T offers more I/O points and faster outputs, making it a direct upgrade while retaining compatibility with existing expansion modules and software.

2. What software is required to program this controller?
You need Schneider Electric’s SoMachine or EcoStruxure Machine Expert – Basic. Both support the full feature set, including Ethernet configuration and PID tuning.

3. Is the Ethernet port isolated from the internal logic?
No, the Ethernet port is not isolated. However, it meets EMC requirements for industrial environments and includes transient protection according to EN/IEC 61000-4-4.

4. How do I reset the controller after a short-circuit event on an output?
The protection circuit automatically resets after approximately 1 second once the overload is removed. No manual intervention is required.

5. Can I use the USB port for permanent communication with a HMI panel?
The USB port is primarily designed for programming and temporary connection. For permanent communication, use the Ethernet or serial RS485 links instead.
