Schneider TM200C40U Easy Modicon M200 Logic Controller
Product Introduction
The Schneider TM200C40U expands the Easy Modicon M200 platform with a 40 I/O capacity and sink‑type transistor outputs. This logic controller features 24 inputs and 16 transistor outputs using negative logic (sink), making it ideal for applications where the load connects to the positive supply rail. It operates on a 24V DC supply and includes 4 high‑speed inputs, 4 fast inputs, and 16 regular inputs. Two outputs (Q0, Q1) serve as fast channels for PWM and PTO functions. The TM200C40U supports Modbus communication, PID regulation, and high‑speed counting, delivering versatile control for complex automation systems.
Technical Specifications
The TM200C40U runs on a rated supply of 24V DC , with an acceptable range of 20.4 to 28.8V. Power consumption is remarkably low at just 10W at maximum I/O load. The controller includes 24 discrete inputs accepting 24V DC logic, with a guaranteed ON voltage of ≥15V and OFF voltage of ≤5V. Input current is 7 mA with 3.3 kΩ impedance, conforming to type 1 sink/source logic per EN/IEC 61131‑2.
For outputs, the TM200C40U provides 16 transistor channels using negative logic (sink). Q2 through Q15 are standard transistor outputs rated at 0.5A each, while Q0 and Q1 serve as fast outputs capable of 100 kHz operation in PWM or PLS mode. These fast outputs support positioning functions with 2 channels at 100 kHz. The outputs feature overload and short‑circuit protection at 3.8A, with automatic reset after 1 second. Maximum leakage current is only 0.1 mA, and voltage drop stays below 1V. Outputs are grouped into three commons: COM0 and COM1 rated at 2A each, and COM2 rated at 4A.
Response times vary by input type. High‑speed inputs switch in 5 µs. Fast inputs respond in 35 µs (on) and 100 µs (off). Regular inputs I8–I13 switch in 35 µs (on) and 100 µs (off), while I14–I23 are slightly slower at 55 µs (on) and 125 µs (off). Standard outputs have a fixed response time of 1 ms for both on and off transitions. You can also configure input filtering at 0, 3, or 12 ms to reject electrical noise.
High‑Speed Counting and Motion Control
The TM200C40U excels in motion‑related applications. Its fast inputs support high‑speed counting (HSC) modes including quadrature (x1, x2, x4), pulse/direction, single phase, and CW/CCW, all at 100 kHz with 32‑bit resolution. You can use these for encoder feedback, flow metering, or position tracking. Additionally, the two fast outputs (Q0, Q1) provide PWM for motor speed control and PLS for stepper or servo pulse generation. The built‑in adjustable PID regulator handles up to 14 simultaneous loops, making temperature, pressure, and flow control straightforward.
Memory and Data Management
Program memory includes 512 bytes of internal flash, storing up to 10,000 instructions. An optional 32 GB micro SD card expands storage for data logging, recipe management, and firmware updates. The real‑time clock maintains accurate time with drift of ≤90 seconds per month at 25°C. A BR2032 lithium battery preserves clock data and program backups for up to 3 years during power interruptions.
Communication and Connectivity
Connectivity on the TM200C40U includes a USB mini B port for programming via SoMachine‑Network at 12 Mbit/s. Two non‑isolated serial links are provided: serial 1 with RS485, and serial 2 configurable for RS232 or RS485. An isolated RS485 interface is also available on serial 2. These support Modbus master/slave protocols in RTU or ASCII modes, with baud rates from 1.2 to 115.2 kbit/s. You can expand I/O by adding up to 4 expansion modules , reaching a total of 144 discrete outputs for transistor systems or 64 for relay systems.
Mechanical and Environmental Ratings
The TM200C40U carries an IP20 rating with the protective cover installed. Operating temperature ranges from 0 to 55°C for horizontal mounting, with storage from -25 to 70°C. It withstands vibration of 3.5 mm at 5–8.4 Hz and 1 gn at 8.4–150 Hz on DIN rail, or 3.5 mm at 5–8.7 Hz and 2 gn at 8.7–150 Hz for panel mounting. Shock resistance is rated at 15 gn for 11 ms and 30 gn for 6 ms. Relative humidity can reach 95% without condensation, and the unit operates at altitudes up to 2000 meters.
Insulation is rated at 500V AC between inputs and logic, between output and logic, and between output groups. The supply‑to‑logic insulation is 500V DC. The controller meets CE, CSA, cULus, IACS E10, and RCM certifications.
Dimensions and Mounting
The TM200C40U has a wider footprint to accommodate its 40 I/O points, measuring 175 mm (W) x 90 mm (H) x 70 mm (D) . Mount it on a standard DIN rail (TH35‑15 or TH35‑7.5 per IEC 60715) or on a panel using an optional fixing kit. All connections use removable screw terminal blocks for easy wiring and maintenance. The power supply connects via a 3‑terminal block, inputs and outputs via dedicated terminal blocks, and serial link 1 via a 4‑terminal block.
For wiring, keep unshielded input cables under 50 meters. Fast and high‑speed inputs require shielded cables shorter than 10 meters. Output cables can run up to 150 meters unshielded.

Frequently Asked Questions (FAQ)
1. What is the difference between TM200C40U and TM200C40T?
The TM200C40U uses sink logic (negative) for its transistor outputs, while the TM200C40T uses source logic (positive). The U version also has lower power consumption (10W vs 24W) and different common ratings (2A/4A vs 3.5A). Choose based on your load wiring requirements.
2. Can I mix sink and source output modules with this controller?
Yes, you can connect up to 4 expansion modules of either sink or source type. However, the onboard outputs are fixed as sink type on the TM200C40U .
3. What is the maximum output frequency for the fast outputs?
Q0 and Q1 support 100 kHz in PWM/PLS mode, making them suitable for stepper motor control and high‑speed pulse generation.
4. Does the controller support Ethernet communication?
This base model does not include Ethernet. Nevertheless, you can use the built‑in serial links (RS232/RS485) with Modbus protocols for networking, or add an optional communication module.
5. How many expansion modules can I connect, and what is the total output capacity?
You can add up to 4 expansion modules . For transistor output systems, the total discrete outputs can reach 144; for relay systems, the maximum is 64 outputs.
