Infineon is applying its new ISOFACE Digital Input technology to a range of its galvanically isolated interfaces for industrial control and automation applications. The product family ISO1I811T and ISO1I813T was recently demonstrated at the Embedded World 2011 tradeshow.
The new ISOFACE Digital Input products offer an integrated galvanic isolation of 500 V a.c. (EN60664-1, UL508) based on the proven technology already used in Infineon’s ISOFACE Digital Output products. This technology provides robust galvanic isolation between the inputs – such as sensors or switches – of a control system on the one hand and the microcontroller or bus ASIC on the other hand. The high level of functional integration, combined with energy efficiency, makes these products suitable for highly compact industrial control solutions such as input cards or sensor modules. Compared with alternative solutions, they are said to enable up to four times more channels on the same printed circuit board area.
The ISOFACE Digital Input products sample information from multiple digital sources – such as sensors – in the automation system and transfer it to the CPU. The solution offers communication frequencies of up to 500 kHz, so that they are suited for high-precision or high-speed applications like bottling machines or paper producing and printing equipment.
To improve the EMI (electromagnetic interference) robustness of the control systems, each of the eight inputs (according to IEC61131-2/Type 1/2/3) of the ISO1I813T has individually programmable deglitching filters. The product’s channel-specific diagnostic capability supports detection of failures like input wire break between a sensor and an IC input. Furthermore, the device’s supply voltage on the input side is monitored and, in case of failures, a two-staged warning signal is sent to the CPU.
