Schneider Electric TM221C16R Programmable Logic Controller

Schneider Electric's TM221C16R Modicon M221 logic controller is a compact-format PLC designed for small-scale automation tasks. It provides 16 I/O points, including 7 relay outputs, and operates from a 100–240 V AC supply. The module uses screw-terminal connections for robust field wiring and supports Modbus communication, enabling straightforward integration with other devices on a control network. Belonging to the Modicon M221 family, the TM221C16R delivers a compact, reliable logic control solution in a small footprint suitable for panel mounting. With its 16 I/O and seven relay outputs, it consolidates essential sensing and actuation in a single module, reducing wiring complexity in space-constrained installations. The 100–240 VAC input range simplifies power distribution for light automation projects, and the relay outputs provide direct switching capability for external devices without requiring additional interface hardware. This model is intended for straightforward machine control and sequencing in compact control panels, and it can be used alongside other M221 components to build small, scalable automation solutions.
