Modicon M241-24I/O TM/T2UK Programmable Logic Controller
The Modicon M241-24I/O TM/T2UK is a compact and powerful PLC from Schneider Electric's M241 series, designed for machine control and industrial automation. This controller combines a high-performance CPU with integrated I/O and Ethernet connectivity, offering a cost-effective solution for applications requiring up to 40 I/O points (discrete and relay outputs). The TM/T2UK variant is specifically tailored for the UK market with appropriate voltage and certification.
Processor and Performance
Equipped with a dual-core ARM Cortex-A9 processor running at 1 GHz, the M241 provides rapid program execution and fast I/O scanning. User memory is 8 MB for program storage and 4 MB for data, with built-in SD card slot for data logging and recipe management. The PLC supports up to 64 tasks and can handle complex motion and logic simultaneously.
Integrated I/O Configuration
The base unit includes 24 digital inputs (24 VDC, sink/source) and 16 relay outputs (2 A, 250 VAC), yielding a total of 40 I/O points. Additionally, it features 2 analog inputs (0-10 V) and 2 analog outputs (0-10 V or 4-20 mA) for handling analog signals. Expansion is possible via up to 7 optional I/O modules on the local bus, extending capacity to several hundred points.
Communication and Networking
The PLC is equipped with two Ethernet ports (10/100 Mbps) supporting EtherNet/IP, Modbus TCP, and OPC UA. One port can be used for programming and HMI, while the other for fieldbus communication. It also includes one RS-232/RS-485 serial port for legacy device connectivity and a USB host port for programming and data transfer.
Programming Environment
Programming is done using Schneider Electric's EcoStruxure Machine Expert software, which supports all IEC 61131-3 languages. The software includes advanced debugging tools, simulation, and visual system design. Users can create custom function blocks and leverage pre-built library functions for motion control, PID, and communication.
Motion Control Capabilities
The M241 supports integrated motion control for up to 4 axes, including positioning, electronic gearing, and camming. It can interface with servo drives via EtherCAT or CANopen, providing synchronized multi-axis movements for packaging, printing, and pick-and-place machines.
Applications
Typical applications include textile machinery, packaging lines, conveyors, and small material handling systems. The M241 is also suitable for OEM equipment where space is limited but performance demands are high.
Environmental and Electrical Data
Operating temperature range is 0 to 55°C, with humidity up to 95% non-condensing. The PLC is rated for 24 VDC input power with reverse polarity protection. It complies with CE, UL, and CSA standards, ensuring global acceptance.
Installation and Commissioning
Installation involves DIN-rail mounting and wiring of I/O terminals with spring-clamp connectors. Commissioning is streamlined with auto-discovery of expansion modules and a guided initial setup in the software. The PLC also features a built-in web server for remote monitoring and diagnostics.
In summary, the Modicon M241-24I/O TM/T2UK delivers a powerful yet compact automation platform, ideal for modern machine builders seeking connectivity, performance, and ease of use.
