The TM221CE16R belongs to the Modicon M221 range of logic controllers from Schneider Electric. It delivers a balanced mix of digital and analog I/O, relay output capability, and integrated Ethernet communication. Designed for simplicity and efficiency, this controller supports up to four expansion modules, making it highly adaptable for various automation tasks. Its compact form factor and wide input voltage range further enhance its suitability for diverse industrial environments.
This controller operates on a rated supply voltage of 100 to 240 V AC, with limits between 85 and 264 V AC. It supports network frequencies of 50 or 60 Hz. The inrush current reaches a maximum of 40 A, while power consumption stands at 49 VA with a full set of expansion modules and 33 VA without them. Additionally, it provides a sensor power supply of 24 V DC at 250 mA, which is sourced directly from the controller.
The TM221CE16R offers a total of 16 discrete I/O points. Specifically, it includes 9 discrete inputs that comply with IEC 61131-2 Type 1 standards. These inputs operate at 24 V DC and can be configured as sink or source logic. Furthermore, the controller features 2 analog inputs with a 0 to 10 V range and 10-bit resolution. For outputs, it provides 7 relay outputs that are normally open, supporting voltages from 5 to 125 V DC and 5 to 250 V AC, with a maximum current of 2 A per output.
Built-in Ethernet connectivity is a standout feature of the TM221CE16R. It includes an RJ45 port supporting 10BASE-T/100BASE-TX, with Modbus TCP client/server and Ethernet/IP adapter capabilities. Moreover, it offers a mini B USB 2.0 port for programming and a non-isolated serial link with RS232/RS485 interfaces. This serial port supports Modbus RTU/ASCII protocols, making the Modicon M221 controller versatile for both new and legacy systems.
The controller boasts a memory capacity of 256 kB RAM for the user application and data, alongside another 256 kB for internal variables. It also features 256 kB of built-in flash memory for data backup. The execution time for 1,000 instructions is an efficient 0.3 ms, with Boolean instruction execution taking just 0.2 µs. Additionally, the real-time clock ensures accurate time-stamping, with a drift of only 30 seconds per month at 25 °C.
Four fast inputs are available on the TM221CE16R, capable of operating in high-speed counter (HSC) mode at frequencies up to 100 kHz. These inputs support single-phase, A/B, and pulse/direction control signals. The counting capacity is 32 bits, which suits precise position or speed monitoring applications. The response time for these fast inputs is as low as 5 µs for turn-on and turn-off, ensuring rapid reaction to external events.
The two analog inputs provide a 10 mV LSB value and a conversion time of 1 ms per channel, plus one controller cycle. They feature an absolute accuracy error of ±1% of full scale. The inputs can withstand permanent overloads of ±13 V DC and temporary overloads of ±30 V DC for up to 5 minutes. Their high impedance of 100 kOhm minimizes signal loading, preserving measurement integrity.
Relay outputs on the TM221CE16R are rated for various loads, including inductive and resistive types. For instance, they support 100,000 cycles at 240 V AC / 120 VA (inductive AC-15) and up to 300,000 cycles at 240 V AC / 160 VA (resistive AC-12). The mechanical durability exceeds 20 million cycles, while the minimum load is specified at 1 mA at 5 V DC. Protection against short circuits is not built-in, so external fusing is recommended for high-current applications.
The Modicon M221 controller supports mounting on a top hat TH35-7.5/15 rail conforming to IEC 60715, as well as panel or plate mounting with a fixing kit. Its compact dimensions are 90 mm in height, 70 mm in depth, and 95 mm in width. This small footprint allows for efficient use of cabinet space, especially in installations with multiple controllers or expansion modules.
For horizontal installation, the operating temperature ranges from -10 to 55 °C, while vertical installation supports -10 to 35 °C. Storage temperatures can vary between -25 and 70 °C. The relative humidity for both operation and storage is 10 to 95% without condensation. With the protective cover in place, the TM221CE16R achieves an IP20 degree of protection, safeguarding against solid objects larger than 12.5 mm.
Vibration resistance is rated at 3.5 mm for frequencies from 5 to 8.4 Hz, and 1 gn from 8.4 to 150 Hz on both symmetrical rail and panel mounting. Shock resistance reaches 98 m/s² with an 11 ms test wave duration. These robust mechanical characteristics ensure reliable operation in environments subject to continuous vibration or occasional impacts, such as those found in manufacturing and material handling.
The TM221CE16R demonstrates high immunity to electromagnetic disturbances. It withstands electrostatic discharge of 4 kV contact and 8 kV air, radiated fields up to 10 V/m, and fast transients of 2 kV on power lines. Surge immunity includes 2 kV common mode on AC power lines. Conducted and radiated emissions comply with EN/IEC 55011 Class A limits, ensuring that the controller does not interfere with nearby sensitive equipment.
Insulation ratings for the Modicon M221 include 2300 V AC between output and internal logic, 500 V AC between input and internal logic, and 1500 V AC between supply and ground. The controller also meets EN/IEC 61010-2-201 and EN/IEC 61131-2 safety standards. Certifications include RCM, DNV-GL, ABS, IACS E10, LR, EAC, CSA, and cULus, confirming its compliance with international marine and industrial requirements.
Proper installation ensures optimal performance and longevity for the TM221CE16R. Begin by mounting the controller securely on a DIN rail or panel, following the provided mounting kit instructions. Ensure adequate clearance around the unit for ventilation and cable routing. The terminal blocks are removable, simplifying wiring and maintenance. Connect the AC power supply to the designated 3-terminal block, observing the correct polarity and voltage limits. For inputs and outputs, use the removable screw terminal blocks. Shielded cables are recommended for fast inputs over distances up to 10 meters to minimize noise. Unshielded cables can be used for digital inputs and outputs up to 30 meters, while analog inputs should be limited to 1 meter with shielded cable to preserve signal accuracy. Finally, connect the Ethernet cable to the RJ45 port for network integration.
