TM221C16R Schneider Electric – Modicon M221 Logic Controller, 16 I/O, 9 DI / 7 Relay Outputs, 100–240 V AC
The Schneider Electric TM221C16R is a compact Modicon M221 logic controller (PLC) for hardwired machine architectures. It combines 9 discrete inputs, 7 relay outputs and 2 embedded analog inputs in a 95 mm-wide housing, and it runs directly from a 100–240 V AC supply. It is programmed with EcoStruxure Machine Expert – Basic (formerly SoMachine Basic) and is a popular choice for simple machines such as pumps, conveyors, packaging units, HVAC equipment and small automation cells.
