Product Introduction
The Schneider Electric TM218LDA40DR4PHN is a Modicon M221 logic controller from the Modicon M2xx family, designed for cost-effective, compact, and scalable machine control. Tailored for original equipment manufacturers (OEMs) and machine builders, this controller provides both flexibility and performance in discrete and simple process automation applications.
Equipped with 40 I/O points (24 digital inputs and 16 relay outputs), two analog inputs, embedded Ethernet, and serial communication ports, this compact PLC simplifies installation while reducing wiring needs. With EcoStruxure Machine Expert (formerly SoMachine Basic) as its configuration environment, the M221 makes development, commissioning, and diagnostics quick and efficient.
Built to operate in harsh industrial environments, the TM218LDA40DR4PHN offers a powerful, all-in-one solution for control applications that demand reliability, connectivity, and ease of use.
