Schneider Electric TM221CE40T Modicon M221 40 I/O Ethernet Transistor Logic Controller

The Schneider Electric TM221CE40T is a Modicon M221 logic controller with 40 discrete I/O — 24 inputs (4 fast) and 16 transistor outputs (2 fast) — supplied from 24 V DC. Built-in Ethernet RJ45 (Modbus TCP client/server, EtherNet/IP adapter) joins USB and RS232/RS485 serial ports, and each output switches up to 0.5 A with up to 7 local expansion modules supported.

Selection Notes

The TM221CE40T pairs the M221's largest compact I/O count (40 points) with native Ethernet, so pick it over the non-Ethernet 40 I/O model when the line needs Modbus TCP or EtherNet/IP reporting without a separate gateway module. Its two 100 kHz fast outputs (Q0-Q1) still support PTO/PWM/PLS for basic motion, while the remaining transistor outputs handle discrete switching at up to 4 A per common.
