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

The Schneider Electric TM221CE24T is a Modicon M221 logic controller with 24 discrete I/O — 14 inputs (4 fast) and 10 transistor outputs (2 fast) — supplied from 24 V DC. It adds an integrated Ethernet RJ45 port (Modbus TCP client/server, EtherNet/IP adapter) alongside USB and RS232/RS485 serial, switching up to 0.5 A per output channel.

Selection Notes

Pick the TM221CE24T over a non-Ethernet M221 when the machine needs native Modbus TCP or EtherNet/IP connectivity without an add-on gateway — the built-in 10/100 Mbit RJ45 port also handles the DHCP client and TCP server/client roles needed for SCADA polling. At 24 I/O (14 DI/10 DO) it sits below the 40-point models, so use it for compact machines where two fast outputs (100 kHz PTO/PLS) are enough for a single-axis positioning task.
