Description
About the TM241CE24R
About the TM241CE24R
The Schneider Electric TM241CE24R is a Modicon M241 logic controller with 24 discrete I/O - 14 inputs (8 fast) and 6 relay outputs plus 4 transistor outputs (4 fast) - running from a 100-240 V AC supply. It adds an embedded Ethernet port for Modbus TCP and EtherNet/IP alongside USB and dual RS232/RS485 serial ports.

Selection Notes
The TM241CE24R's embedded Ethernet port adds Modbus TCP, EtherNet/IP, FTP, and OPC UA server connectivity that transistor-only, non-Ethernet M241 base units lack, making it the base unit of choice where the controller needs to sit on a plant network rather than communicate over serial links alone. Its 6 relay outputs (2 A, up to 250 V AC) switch contactor coils and pilot loads directly without an interposing relay, while the 4 transistor outputs (4 fast, 100 kHz PLS) still support basic pulse-train positioning where the relay outputs cannot. The 100-240 V AC supply removes the need for a separate 24 V DC power supply in panels already running on line voltage.
Applications
Compact-machine automation needing plant-network connectivity - packaging, material handling, and machine-control panels running Modbus TCP or EtherNet/IP alongside relay-driven contactor and pilot-device switching.
