TM221CE24T Modicon M221 24 I/O Transistor PNP Ethernet Logic Controller | Schneider Electric

The Original New Schneider Electric TM221CE24T Modicon M221 Logic Controller is a compact, high-performance programmable logic controller (PLC) designed for small to medium machine control applications requiring high-speed output switching and network connectivity. Part of the Modicon M221 range, this nano PLC provides 24 mixed I/O points (14 inputs, 10 transistor PNP outputs) with 2 analog inputs and 4 fast inputs for high-speed counting and interrupt tasks. Featuring 256 KB memory, integrated Ethernet, USB, and serial communication ports, and supporting up to 7 local TM3 expansion modules, the TM221CE24T offers a scalable solution for industrial automation systems. Configured via the free SoMachine Basic software, it delivers benchmark performance with fast transistor outputs for demanding machine control applications.
