Schneider Electric TM221CE16R Programmable Logic Controller

The Schneider Electric TM221CE16R Modicon M221 PLC Module delivers compact, Ethernet-enabled control for small- to mid-sized automation tasks, featuring nine 24 VDC digital inputs and seven relay outputs. With approximately 256 KB of program memory and TM3 expansion module support, it is well-suited for packaging machines, conveyors, small production lines, and OEM equipment that require reliable PLC control. In industrial applications, it provides integrated I/O and communications for material handling, food and beverage processing, water treatment, and other small to mid-sized machinery, including Ethernet, USB, and RS-485 serial connectivity. DIN rail mounting, 24 VDC input, a -10°C to 55°C operating range, and the ability to connect via Ethernet, USB, or RS-485 make it a flexible choice for compact automation when space and network capability matter. Common replacements include TM221CE24R, TM221CE40R, and TM241CE40R.
