Specifications Parameter Category Details Manufacturer & Series Schneider Electric, Modicon TM221 (M221 Nano Series) Complete Model Number TM221CE16U Product Type Compact Logic Controller (PLC) CPU Performance High-speed processor, typical execution speed: ~0.5 µs per Boolean instruction. Embedded I/O 16x Digital Inputs (24V DC, sink/source configurable, 4 of which can be used as high-speed counters up to 10 kHz). No embedded digital outputs on this base model. Outputs must be added via expansion modules. Expansion Capability Supports up to 4 TM3 expansion modules (maximum of 28 I/O modules across the system, including the base controller's inputs). User Memory ~16 KB for user program (ladder logic). Data Memory ~8 KB for retentive data. Real-Time Clock (RTC) Integrated with battery backup (CR2032 battery, not included in standard delivery). Communication Ports 1x Ethernet Port (RJ45): Modbus TCP (client/server), Ethernet/IP adapter, SoMachine Basic network (for programming, HMI connection, etc.). 1x Serial Port (Mini DIN): Modbus (Master/Slave), ASCII, SoMachine Basic network. Programming Standard Compliant with IEC 61131-3. Supported Languages Ladder Diagram (LD) exclusively in EcoStruxure Machine Expert - Basic. Programming Software EcoStruxure Machine Expert - Basic (free software). High-Speed Functions 4x High-Speed Counters (HSC) (up to 10 kHz, embedded in inputs I0 to I3). 2x Pulse Train Outputs (PTO) (available via optional TM3 expansion module). Power Supply 24V DC (19.2 - 28.8V DC). Power Consumption Typically 10W (from 24V DC supply). Operating Temperature 0°C to +55°C Storage Temperature -25°C to +70°C Relative Humidity 5% to 95% (non-condensing) Protection Rating IP20 (for installation inside an enclosure).
