Schneider Electric TM221C40U Modicon M221 Logic Controller 40 I/O Transistor NPN. The Schneider Electric Modicon M221 Logic Controller, part number TM221C40U, is a compact and efficient machine controller designed for OEM machines and small plant automation. This versatile logic controller operates on a 24 V DC supply and features a robust I/O configuration, including 24 discrete inputs (with 4 fast inputs conforming to IEC 61131-2 Type 1) and 2 analogue inputs (0-10 V). For outputs, it provides 16 transistor outputs, 4 of which are fast outputs, capable of 0.5 A at 24 V DC. With a total of 40 discrete I/Os, it supports up to 7 local or 14 remote I/O expansion modules. Key functionalities include 14 adjustable PID regulation loops, 4-axis pulse/direction positioning, and a real-time clock. Connectivity is comprehensive with a USB 2.0 port, an RS485 serial link, and a second RS232/RS485 serial link. Its 256 kB memory for user application and data RAM ensures efficient program execution. This controller is ideal for diverse industrial applications across Egypt and the Gulf, such as water treatment plants, food and beverage processing, textile manufacturing, cement production, and oil and gas facilities.
