Schneider Electric TM221ME32TK Logic Controller

Schneider Electric's Modicon M221 TM221ME32TK is a compact, book‑style logic controller that delivers 32 I/O for small to mid‑size automation tasks. It provides 16 digital inputs (12 regular, 4 high‑speed) and 16 digital outputs (14 regular transistor outputs, 2 high‑speed transistor outputs), plus 2 analog inputs, all powered from a 24 V DC supply. The device includes a Ethernet port for networked control, a serial line port for legacy field devices, and a USB mini‑B programming port for local setup and debugging. Housed in the Book form factor (HE 10), it is designed to fit into tight control panels and simplify wiring in compact machines. The TM221ME32TK uses PNP transistor outputs, enabling sourcing to actuators, and is well suited for applications such as packaging lines, conveyors, machine tools, and other control tasks where reliable local control and Ethernet connectivity are needed. With integrated Ethernet communication and USB programming alongside traditional serial connectivity, this M221 model supports straightforward integration with supervisory systems and Schneider components while remaining a dependable, space‑efficient PLC option for small automation projects.
