S-DIAS Strain Gauge Input Module AI 022
with 2 analog inputs
The S-DIAS AI 022 strain gauge input module is used to analyze meas-
uring bridges (e.g. strain gauge load cells). With a 24-bit resolution,
measurement values with an overall accuracy of 0.035 % are provided.

(1) The measurement range is defined for a 50 % distention of the load cell.
(2) These are typical values with an active Sinc4 filter and measurement range of 2 mV/V
(3) To maintain the accuracy of the analog channel measurement, a system calibration with the sensor is required
whereby the null point and full-scale deflection are calibrated. The system must be re-calibrated when a sensor is
replaced or the measurement range changed. Basically, the null point calibration is performed followed by the
calibration for the full-scale deflection. The full-scale deflection can only be calibrated between 50 and 100 % of
the positive measurement range.

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 +24 V supply cannot exceed 1.6 A!
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 documentation
under "Electrical Requirements".
Si ce module S-DIAS est connecté à un module d’alimentation S-DIAS suivi de
plusieurs modules S-DIAS, le courant total des modules utilisés doit être déterminé
et vérifié.
Le courant total de l'alimentation +24 V ne peut pas dépasser 1,6 A!
Le courant total de l'alimentation +5 V ne peut pas dépasser 1,6 A!
Le cahier des charges pour le courant peut être trouvé dans la documentation
spécifique au module sous "Spécifications électriques".
