Schneider Electric TM221CE16T Programmable Logic Controller

Schneider Electric's TM221CE16T is a compact Modicon M221 logic controller with built‑in Ethernet that provides 16 discrete I/O (9 digital inputs and 7 digital outputs) with transistor PNP outputs operating from a 24 V DC supply. It features a single Ethernet port (10BASE-T/100BASE-TX) for straightforward Modbus TCP/IP communications and can function as a Modbus TCP/IP slave on a network. The TM221CE16T is designed for DIN-rail mounting and is compatible with TM3 expansion modules, enabling local, remote, or distributed I/O configurations to scale with your machine or small system. This makes it well suited for low‑to‑mid complexity automation tasks such as small packaging lines, conveyors, and basic machine control where reliable, compact control and Ethernet connectivity are required. As part of the Modicon M221 family, the TM221CE16T emphasizes fast I/O handling and a straightforward programming model for simple logic tasks while maintaining compatibility with Schneider Electric’s broader EcoStruxure automation ecosystem. DIN‑rail mounting, 24 V DC operation, and an integrated Ethernet interface collectively support quick integration with a variety of HMI/SCADA setups and other Ethernet-enabled controllers.
