Isolated Industrial Interface

Infineon’s ISOFACE™ for industrial automation

Infineon’s ISOFACE™ are highly reliable industrial interface ICs with integrated isolation that can improve reliability by 5-times and cut the product launch time of industrial automation systems by 50 percent. ISOFACE™ sets new standards in diagnostic capabilities, reducing unscheduled downtimes to a minimum. Take advantage of the various benefits of Infineon’s solution for isolated industrial interface ICs.

Isolated industrial interface ICs are divided into two subcategories: The ISOFACE™ output switches and the ISOFACE™ digital input ICs

Infineon’s galvanically isolated 8-channel ISOFACE™ output switches can be used to drive any kind of resistive, inductive, or capacitive loads. Each of the switch outputs is fully short-circuit proof and overtemperature protected, which is another aspect underscoring the extreme ruggedness of the ISOFACE™ output switches. The level of functional integration by Infineon’s ISOFACE™ output switches improves system stability and reliability significantly and reduces consumed PCB area drastically.

Infineon’s ISOFACE™ digital input ICs are an intelligent system solution offering robust galvanic isolation between the µC on the control side and the 24V factory floor environment, frequently referred to as the “process side”. They can be directly connected to digital inputs like sensors or switches and to microcontroller or Bus-ASIC. Compared to alternative solutions, ISOFACE™ digital input ICs enable up to four times more channels on the same PCB area. A robust galvanic isolation is integrated. This high level of integration density combined with the low power consumption is a key enabler for highly compact industrial control products.

Key benefits of ISOFACE™ isolated industrial interface ICs

Ready for harsh environments

Factory automation systems have to meet IEC 61131-4 requirements both in terms of input and output characteristics, as well as in isolation robustness (EN 61010-1). Most of these systems are deployed in very harsh environments and therefore have to withstand extreme EMI disturbances (surge, burst, RF) according to IEC 61000-4. Infineon’s ISOFACE™ isolated industrial interface ICs are prepared for designs, which are exposed to EMI disturbances at system-level.

Made to last

Contrary to some alternatives, Infineon’s isolated industrial interface products have integrated galvanic isolation, truly short-circuit proof outputs, and strong designed-in EMI robustness. This does not only ease the system design process significantly but results in longevity as well.

Sets the standard in diagnostics

It is critical to reduce system downtimes to virtually zero. For continuous verification of the system-integrity and in case of problems in minimizing costly system downtimes by factors of up to 30, Infineon’s ISOFACE™ isolated industrial interface products contain one-of-a-kind support for diagnostics. That is why leading factory automation companies are choosing Infineon’s ISOFACE™ isolated industrial interface products.
