The "Elektronik" readers got it right, clearly seeing the unique value of ISOFACE™ digital input ICs. Almost 12.000 out of some 100.000 readers of the print edition of the German electronics magazine cast their ballot. ISOFACE™ digital input IC was ranked the third 'Product of the Year 2012' within the automation section.
Designed by Infineon the ISOFACE™ product family comprises galvanically isolated 8-channel high-side switches and 8-channel digital input ICs. ISOFACE™ products integrate a versatile microcontroller/ASIC interface, robust galvanic isolation and rugged output switches or intelligent digital input functionality. ISOFACE™ thus minimizes the number of components required to design a complete system solution. This unique level of integration enables compact and cost-efficient industrial control solutions offering much higher system stability and reliability. ISOFACE™ is the ideal solution to meet the galvanic isolation challenges of industrial automation systems such as programmable logic controllers (PLCs), distributed control systems, industrial PCs, general control equipment and sensor input modules.
Galvanically isolated output switches
ISOFACE™ output switches include a rugged and intelligent galvanically isolated interface between the microcontroller or the bus ASIC and the power switches. These 8-channel high-side switches can drive any kind of resistive, inductive or capacitive loads.
Galvanically isolated digital input ICs
ISOFACE™ digital input ICs offer robust galvanic isolation between digital sensor inputs and microcontrollers or bus ASICs. Diagnostic feedback helps maximize equipment uptime.
Best fit for industrial isolation challenges
Most industrial automation applications require robust galvanic isolation between the control and process sides to decouple ground shifts resulting from the difference in electric current flow between the two sides of the system. ISOFACE™ offers a complete and robust system solution to meet this challenge.
