Schneider TM241CEC24T PLC Controller Modicon M241
The Schneider Electric TM241CEC24T is a programmable logic controller from the Modicon M241 series. It is designed for motion control applications requiring high-speed I/O processing and real-time communication. The CPU integrates 14 digital inputs and 10 digital outputs (including 4 fast transistor outputs for pulse trains). The controller features built-in Ethernet and CANopen master ports.
CPU Performance
The controller uses a 32-bit ARM Cortex-M3 at 120 MHz with 128 KB RAM and 256 KB flash memory. Typical bit instruction execution: 0.06 µs. Application memory: 128 KB. Retentive data: 8 KB (EEPROM backed). The real-time clock (RTC) has a 14-day supercapacitor backup. Cycle time for 1000 instructions: < 0.5 ms.
Onboard I/O Details
Digital Inputs (14): 12 sinking (24V DC) and 2 fast inputs (100 kHz for encoders). Input current: 5 mA. Digital Outputs (10): 6 relay outputs (2A, 30V DC/250V AC) and 4 transistor outputs (0.5A, 24V DC, two of them are 100 kHz pulse train outputs). Outputs have short-circuit protection and LED indication. The total current per common: 8 A for relays.
Communication Ports
1 x Ethernet (10/100) supporting Modbus TCP, EtherNet/IP, and PROFINET (with firmware V2.0).
1 x CANopen master (DB9) for up to 32 nodes, 1 Mbps.
1 x Non-isolated RS-485 (terminal block) for Modbus RTU or ASCII.
1 x USB mini-B (programming port).
1 x SD card slot (up to 32 GB) for data logging and program backup.
Expansion Capabilities
The TM241CEC24T can expand up to 7 TM3 digital/analog I/O modules via the rear bus, for a total of 96 digital I/O or 28 analog I/O. It also supports TM3 bus couplers for remote I/O over CANopen. Motion control: up to 4 axes using pulse outputs or CANopen drive profiles (CiA 402).
Programming Software
SoMachine (now EcoStruxure Machine Expert) V1.2 or later. Languages: LD, FBD, ST, IL, SFC. The controller supports the PLCopen motion function blocks (MC_Power, MC_MoveRelative, etc.). Integrated web server for diagnostics and machine data visualization.
Power and Environment
Supply voltage: 24V DC (19.2–28.8V). Power consumption: 12W typical. Dimensions: 95 mm x 70 mm x 90 mm (W x H x D). Weight: 0.45 kg. Operating temperature: -10°C to 55°C; storage: -40°C to 85°C. Protection class: IP20. Humidity: 10% to 95% non-condensing. Vibration: 3 g (10–150 Hz).
