The Schneider Electric Modicon TM3 series provides flexible and cost-effective expansion I/O modules specially designed for Modicon M221, M241, and M251 PLCs. These modules expand the capabilities of your controller by adding digital, analog, and mixed I/O, as well as dedicated safety and communication modules.

With the TM3 series, up to 7 modules can be connected directly to the PLC, and the system can be expanded further with an additional bus expansion, ensuring scalability for both small and large automation projects.
