Strengthening the link between the real and the digital world

Digital input and output modules (I/O modules) are key elements of every PLC (programmable logic controller). Specifically, they assume a PLC’s control, communication and actuating functions. But digital I/O modules face an ever-greater list of challenges. These arise from a growing demand for flexible use while their system reliability simultaneous competes for market share.

Evolving customer needs also factor in. A solution’s IP protection and access limitation – as well as its power consumption and system longevity – play decisive roles from the customer perspective. Safety aspects are likewise gaining importance, in particular when controlling drives. In this competitive marketplace, long-term experience is fundamental as are features such as simple, low cost maintenance and data access security.

One of the most crucial components of an I/O module is the switch. Generally speaking, two types of configurations are possible: high-side or low-side. Regardless of the configuration, Infineon offers dedicated solutions that boost your project. Our high-side ISOFACE™ switches are known for their high level of integration and robustness. They also offer galvanic isolation, protection and diagnostic feedbacks in one device. Take a moment to explore Infineon's Industrial PROFET™ (PROtected FET) products. These high-side switches include protection and diagnosis functions to ensure safe system operation of I/O modules. Look further to our OptiMOS™ 5 40V and 60V families which are Infineon’s discrete solutions for I/O modules. They are also thermally optimized and feature the lowest R _DS (on).

The HITFET™ family is Infineon’s answer to all lowside configurations. Built-in protection and intelligence features makes these components ideal for use in PLCs and I/O modules. A one-stop-shop, at Infineon you’ll find all components for your designs from one trusted source. From µC, to security, to power management, to communication, to protection. Enhance your project with solutions for digital I/O modules from Infineon.
