Product Features

 

The Schneider Electric TM221CE40R is a high-performance logic controller from the Modicon M221 series, designed to simplify small and medium-sized automation projects with its integrated features and reliable performance. This all-in-one PLC combines a CPU, 24 digital inputs, 16 relay outputs, and 2 analog inputs in a single compact unit, measuring just 160×70×90 mm and weighing only 0.456 kg. It fits easily into tight control cabinets and reduces installation time by 40% compared to assembling separate components.

 

Engineered for global use, the TM221CE40R operates on a wide 100–240 V AC power supply (50/60 Hz), with a voltage range of 85–264 V AC to handle fluctuations in electrical grids. It consumes just 41 VA without expansion modules and up to 70 VA with maximum expansion, making it energy-efficient for continuous operation. The built-in 24 V DC sensor power supply delivers 250 mA to power field devices, eliminating the need for additional power sources.

 

The TM221CE40R features 24 digital inputs (IEC 61131-2 Type 1) compatible with 24 V DC signals, with selectable sink/source logic. Four of these inputs (I0, I1, I6, I7) function as high-speed inputs with a 5 μs response time, while the remaining 20 inputs offer 35 μs on and 100 μs off response times. Users can adjust the input filter time to 0, 3, or 12 ms to suit specific application needs.

 

For output control, the TM221CE40R includes 16 normally open relay outputs that handle 5–250 V AC or 5–125 V DC loads. Each output supports up to 2 A, with a maximum of 7 A per common terminal, and operates with a 10 ms on/off response time. The relays have a mechanical lifespan of over 20 million cycles and an electrical lifespan of 100,000 cycles at full load, ensuring long-term reliability.

 

Two built-in analog inputs accept 0–10 V DC signals with 10-bit resolution (10 mV per LSB) and 1 ms conversion time per channel. These inputs feature 100 kΩ impedance and overvoltage protection up to ±13 V DC permanently and ±30 V DC for up to 5 minutes, safeguarding against electrical surges in industrial environments.

 

FAQ
 

Q: What are the exact I/O configurations on the TM221CE40R?

A: The TM221CE40R provides 40 total I/O points. It includes 24 discrete inputs, all configurable as sink or source (positive/negative logic) operating at 24 VDC with 7 mA input current. Among these, 4 inputs serve as fast inputs with 5 µs response time. Additionally, the unit features 2 analog inputs with a 0–10 VDC range, 10-bit resolution, and an LSB value of 10 mV. The 16 discrete outputs are relay type, normally open, rated at 2 A per point, with an output voltage range of 5–250 VAC or 5–125 VDC.

Q: What is the memory capacity and backup capability?

A: The controller offers 256 KB RAM for internal variables and user application storage, plus 256 KB built-in flash memory for program and data retention. For extended storage, it supports SD cards up to 2 GB capacity for program archiving and data logging. The real-time clock maintains ±30 seconds per month accuracy at 25°C.

Q: How many expansion modules can be connected?

A: The TM221CE40R supports expansion via the Modicon TM3 expansion module family. It accommodates up to 7 expansion modules, enabling a maximum of 48 additional discrete outputs for relay configurations. This modular architecture allows system scaling from the base 40 I/O to expanded configurations tailored to application requirements.

Q: What is the operating temperature range and environmental ratings?

A: The controller operates in ambient temperatures from -10°C to 55°C (14°F to 131°F). Relative humidity tolerance ranges from 10% to 95% non-condensing for both operation and storage. Relay output mechanical life is rated at 20,000,000 cycles, with electrical life depending on load conditions.
