Schneider Electric TM221C16T Logic Controller

Schneider Electric TM221C16T is a compact Modicon M221 logic controller delivering 16 I/O points on a small DIN-rail module. It provides 9 digital inputs and 7 digital outputs with transistor, PNP (sourcing) outputs at 24 V DC, making it well-suited for simple machine control, sensing, and sequencing tasks. The module supports Modbus RTU/ASCII communications for basic field-level integration and can be programmed with EcoStruxure Machine Expert Basic software. The TM221C16T is DIN-rail mountable (clip-on lock for 35 mm DIN rails) and can be expanded with TM3 expansion modules to increase I/O capacity. This model belongs to Schneider Electric's Modicon M221 family, designed for compact, cost-effective control of small automation tasks while offering the reliability and compatibility of Schneider's EcoStruxure ecosystem.
