General Control Equipment
The ISO1I813T is an electrically isolated 8 bit data
input interface in TSSOP-48 package.
This part is 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 operating sensors of type 1/2/3 in accordance with
IEC61131-2, it is necessary for the device to be wired
with resistors RV and REXT (it is recommended to use
resistors with an accuracy of 2%, in any case < 5% - is
mandatory, temperature-coefficients < 200ppm are
allowed).
An 8 bit parallel µC compatible interface allows to
connect the IC directly to a µC system. The input
interface is designed to operate with 3.3/5V CMOS
compatible levels.
The data transfer from input to output side is realized by
the integrated Coreless Transformer Technology.
