Specification

SEODescription

The Schneider Electric TM221M16TG, part of the Modicon M221 PLC series, is a compact PLC designed for small to mid-sized automation tasks. It features 16 digital inputs and 10 transistor outputs, with the ability to directly connect up to 4 expansion modules for I/O scalability. Supporting Ethernet and serial communication (RS485) with built-in Modbus protocols, it operates on 24V DC or 100-240V AC power and functions reliably in temperatures ranging from -25°C to +55°C. Ideal for manufacturing, HVAC, and water treatment industries, the TM221M16TG Compact PLC offers user-friendly programming via SoMachine Basic software, cost-effective performance, and a small footprint. However, its limited processing power and memory restrict use in complex applications. Its reliability and simplicity make it a popular choice for entry-level industrial automation.
