Programmable logic controller (PLC)

At the heart of most industrial control and factory automation systems is a programmable logic controller (PLC). Commonly referred to as the “brain” of a factory, a PLC controls a wide range of functions by receiving and processing data from sensors and machines. It then uses this data to control and actuate external devices.

Because it’s used in industrial applications, a PLC must be robust. What’s more, a successful design must offer reliability, system stability and 100% interoperability with connected automation systems. Additional factors to consider when engineering a PLC include time to market, space limitations and the high demand for components with a good price-quality ratio.

Infineon understands the needs of its industrial customers and offers dedicated semiconductor solutions that overcome the challenges common to PLC projects. In our top-grade portfolio, you’ll find robust, reliable designs as well as a wide range of products for customizing PLC applications. For instance, discover Infineon’s 32-bit industrial microcontroller family XMC 1000 and XMC4000, designed for the demanding tasks of a PLC. For one of the best-embedded security products on the market, choose the OPTIGA™ Trust product family.

Highly integrated or discrete: switching solutions for PLCs

Digital Input and Output modules (I/O modules) are a key element in each PLC. Our product portfolio of smart low-side and high-side switches covers all existing switching solutions for I/O modules, regardless of their configuration, enabling various diagnostic, protection and isolation features. Additionally, we offer a discrete solution with OptiMOS™ 5 40V and 60V, which is thermally optimized to provide the lowest R _DS (on) and therefore suitable to help overcome challenges your PLC project faces. Take your PLC design to the next level with Infineon.
