Schneider Electric TM221M16R Modicon M221 16 I/O Relay Logic Controller. The Schneider Electric Modicon M221 Logic Controller, part number TM221M16R, is a compact and efficient machine controller designed for OEM machines and small plant automation. This versatile controller operates on a 24 V DC supply and features 8 discrete inputs conforming to IEC 61131-2 Type 1, alongside 2 analogue inputs (0-10 V). For outputs, it provides 8 normally open relay outputs, capable of switching 2 A at voltages from 5-125 V DC or 5-250 V AC, making it suitable for a wide range of control applications. The TM221M16R supports expandability with up to 14 remote I/O expansion modules, offering flexibility for growing automation needs. Communication options include a USB port and two non-isolated serial links (RS485, RS232/RS485) supporting Modbus master/slave protocols. With 256 kB of memory for user applications and data, it is a robust solution for industries in Egypt and the Gulf, such as water treatment, cement, oil and gas, food and beverage, and textiles, ensuring reliable process control and data acquisition.
