TM241CE40T Modicon M241 40 I/O Transistor PNP Ethernet Logic Controller | Schneider Electric

The Original New Schneider Electric TM241CE40T Modicon M241 Logic Controller is a high-performance programmable logic controller (PLC) designed for demanding machine control applications requiring speed, precision, and connectivity. Part of the Modicon M241 range, this compact controller provides 40 mixed I/O points (24 inputs, 16 transistor PNP outputs) with 8 fast inputs and 4 fast outputs for high-speed counting and positioning tasks. Featuring 8 MB program memory, 64 MB RAM, 128 MB built‑in flash memory for user program backup, and an SD card slot (up to 16 GB), it offers scalable memory for complex automation projects. Built‑in Ethernet, dual serial ports, and USB programming port provide flexible connectivity, while embedded CANopen supports fieldbus architectures up to 63 devices. Configured via the free EcoStruxure Machine Expert software, it delivers benchmark performance with fast 2 µs response times for demanding motion and positioning applications.
