Schneider Electric TM221ME16T Programmable Logic Controller

Schneider Electric's TM221ME16T is a Modicon M221 programmable logic controller with 16 I/O—8 digital inputs and 8 transistor outputs (PNP)—and an Ethernet interface for networked control. The screw-terminal TM221ME16T variant is part of the M221 family (the TM221ME16TG is the spring-terminal counterpart), delivering a compact, Ethernet-enabled PLC suitable for straightforward machine automation. It is supported by Schneider Electric's EcoStruxure Machine Expert Basic programming software for ladder or structured text development, making it well suited for standalone machine control, line sequencing, and simple interlocks on small automation projects, with the 16 I/O configuration enabling direct wiring of sensors and actuators on a single controller. The device’s Ethernet connectivity facilitates easy integration with devices across a control network and remote programming or diagnostics.
