Schneider TM200CE40T Logic Controller 40 I/O Transistor Source

Product Introduction

The TM200CE40T controller belongs to the renowned Modicon M200 family. It is specifically engineered for applications that demand fast switching, precise positioning, and reliable DC output control. This model provides 24 discrete inputs and 16 transistor outputs, all within a compact 175 mm wide housing. Its 24 V DC power supply ensures compatibility with standard industrial power systems. Moreover, the integrated Ethernet port supports Modbus TCP/IP for seamless network integration. Many system integrators prefer the TM200CE40T for its high-speed output capabilities and excellent expansion potential.

Technical Specifications

The TM200CE40T integrates 24 inputs and 16 outputs. Among the inputs, four are fast inputs (I2 to I5), four are high-speed inputs (I0, I1, I6, I7), and the remaining sixteen are regular inputs (I8 to I23). The outputs consist of two fast transistor channels (Q0 and Q1) that support PLS, PWM, and PTO modes, plus fourteen standard transistor outputs (Q2 to Q15). Furthermore, the supply voltage ranges from 20.4 to 28.8 V DC, with a maximum power consumption of 18 W at full load. The input logic supports both sink and source configurations, complying with EN/IEC 61131-2 standards.

Output and Input Performance

Specifically, the fast outputs on the TM200CE40T achieve a switching frequency of 100 kHz, making them suitable for pulse train positioning and PWM regulation. The standard transistor outputs respond within 1 ms for both turn-on and turn-off. Each output channel delivers 0.5 A at 24 V DC, with a maximum voltage drop of less than 1 V. For inputs, high-speed channels react within 5 µs, while fast inputs respond in 35 µs (on) and 100 µs (off). Regular inputs I8 to I13 have a response time of 35 µs (on) and 100 µs (off), whereas I14 to I23 respond in 55 µs (on) and 125 µs (off). Configurable filtering options of 0 ms, 3 ms, or 12 ms help suppress electrical noise in challenging environments.

Communication and Connectivity

This controller offers multiple communication ports for flexible connectivity. First, a non-isolated RS485 serial link is accessible via a terminal block. Second, another non-isolated serial port supports both RS232 and RS485 interfaces. Third, an integrated Ethernet port with an RJ45 connector provides 10/100BASE-T and Modbus TCP/IP client/server protocols. Additionally, a USB mini B port enables direct programming through SoMachine-Network. The Ethernet transmission rate reaches 10/100 Mbit/s over distances up to 100 meters. Consequently, the TM200CE40T integrates smoothly into modern industrial networks.

Memory, Battery, and Real-Time Clock

The internal flash memory offers 512 bytes for program backup. An optional 32 GB micro SD card expands data storage for large applications. A BR2032 lithium battery maintains the real-time clock and retains user data for up to 5 years at 25 °C. The backup time during power interruption is approximately 3 years at the same temperature. Furthermore, the clock drift is less than 90 seconds per month, which ensures accurate event logging and time-stamping for critical processes.

Expansion and Positioning Capabilities

The TM200CE40T supports up to four I/O expansion modules. For relay outputs, the total can reach 64 discrete outputs; for transistor outputs, the maximum is 144 points. Moreover, the built-in adjustable PID regulator can handle up to 14 simultaneous control loops. The positioning functions include two channels of PWM/PLS at 100 kHz, ideal for stepper or servo drive control. For high-speed counting, the fast inputs support quadrature (x1, x2, x4), Pulse/Direction, Single phase, and CW/CCW signal types at 100 kHz with 32-bit resolution. This flexibility makes the TM200CE40T an excellent choice for packaging machines, labeling equipment, and small motion systems.

Electrical Protection and Insulation

Protection features are essential for reliable operation. Therefore, the transistor outputs on the TM200CE40T 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 industrial conditions.

Mechanical and Environmental Ratings

The TM200CE40T measures 175 mm wide, 90 mm high, and 70 mm deep. Its net weight is 0.523 kg, 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. 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 is up to 15 gn for 11 ms. The immunity to microbreaks is 2 ms, ensuring stable operation during brief power fluctuations.

Installation and Wiring Guidance

Mount the controller on a standard TH35-15 or TH35-7.5 rail according to IEC 60715. Panel mounting is also possible with an optional fixing 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 convenient maintenance. The power supply connects via a 3-terminal block, while the serial link uses a 4-terminal connector. Proper grounding and shielding practices will maximize performance and noise immunity.

Frequently Asked Questions (FAQ)

1. What is the difference between the TM200CE40T and the TM200CE40R?
The TM200CE40T uses transistor source outputs with 0.5 A DC capacity and supports 100 kHz fast outputs. The TM200CE40R uses relay outputs that can switch AC or DC loads up to 2 A but are slower and less suitable for high-frequency applications.

2. Can I use the fast outputs on the TM200CE40T to control a stepper driver directly?
Yes, the two fast outputs (Q0 and Q1) support PWM/PLS and PTO modes at 100 kHz, making them ideal for directly connecting to stepper or servo drives that accept pulse/direction signals.

3. What software is required to program the TM200CE40T?
You need Schneider Electric's SoMachine or EcoStruxure Machine Expert – Basic. Both platforms support all functions including Ethernet configuration, PID loops, and high-speed counting.

4. How many expansion modules can I add to this controller?
The TM200CE40T supports up to four I/O expansion modules, allowing you to increase total outputs to 144 transistor outputs or 64 relay outputs as needed.

5. Does the TM200CE40T include built-in short-circuit protection on the outputs?
Yes, all transistor outputs have overload and short-circuit protection at 2 A. The protection resets automatically after approximately 1 second once the fault condition is removed.
