with 4 analog inputs 0-22 mA or 4-22 mA
The S-DIAS analog input module AI 047 has four analog inputs
0-22 mA or 4-22 mA with an 18-bit resolution. The voltage supply for
the analog inputs are monitored for under voltage. The analog inputs
are galvanically separated from the S-DIAS bus.

(1) If the upper or lower limit of a measurement range is exceeded, it will display a corresponding status bit.
(2) The filter parameters (frequency and order) for differential mode are depending on the scan rate in mode 2. An
overview can be found in the table below. The frequency responses are shown in the diagrams below.
(3) This is a 1st order IIR filter, which has an adjustable frequency and can also be deactivated. Caution! The SW
filter does not replace the HW filter! The SW filter only functions correctly when the Nyquist-Shannon theorem is
observed.

INFORMATION
If this S-DIAS module is connected to an S-DIAS supply module with
several S-DIAS modules, the total current of the modules used must be
determined and checked.

The total current of the +5 V supply cannot exceed 1.6 A!
The specification for the current can be found in the module-specific
technical documentation under "Electrical Requirements".
