Schneider Electric TM251MESC Programmable Logic Controller

Schneider Electric's TM251MESC is a compact Modicon M251 programmable logic controller designed for machine automation, combining Ethernet connectivity with a CANopen port for fieldbus integration. It supports Modbus TCP and EtherNet/IP communications and OPC UA, powered from a 24 V DC supply for standard industrial power rails. The unit includes a serial line port, a USB mini-B programming port, a dual-port Ethernet switch, and a CANopen port, enabling flexible network topology and direct CANopen master capability. Programmable with Schneider Electric's EcoStruxure Machine Expert software (formerly SoMachine), the TM251MESC supports IEC 61131-3 languages and is suitable for small-to-mid-size machine control tasks such as packaging lines, conveyors, and automated processes across manufacturing environments.
