Digital input/output (I/O) modules
Robust and reliable semiconductor solutions for digital I/O modules
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.
Straight talk about the right switches
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.
