ISO1I811T

The ISO1I811T is an electrically isolated 8 bit Data Input Interface used to detect the signal states of eight independent input lines according to IEC61131-2 Type 1/2/3 (e.g. two-wire proximity switches) with a common ground (GNDFI). For operation in accordance with IEC61131-2, it is necessary for the ISO1I811T to be wired with resistors according to the application diagram. The 8 bit parallel/serial µC compatible interface allows the IC to directly connect to a µC system. The µC interface also supports a direct control mode and is designed to operate with 3.3/5V CMOS compatible levels. The data transfer and isolation from input to output side is realized by the integrated Coreless Transformer Technology.
