4.3.2.1 General Information
The X20AI1744 and X20AI1744-3 modules work with both 4-line and 6-line strain gauge cells. If a 6-line strain
gauge cell is connected, the line compensation no longer functions. This module concept requires compensation
in the measurement system. This compensation eliminates the absolute uncertainty in the measurement circuit,
suchas component tolerances, effective bridge voltage, or zero offset. The measurement precision refers to the
absolute (compensated) value, which will only change as a result of changes in the operating temperature.
The AI1744 analog input module is available in two versions:
Model number
Description
X20AI1744
The module is equipped with a 5kHz input filter for fast signal sequences. It therefore also allows high frequency signals and
disturbances to pass through.
X20AI1744-3
This version is equipped with a slow 5Hz input filter. It is therefore suitable for slow signal sequences and provides good suppres-
sion of high frequency disturbance signals.
•
1 full-bridge strain gauge input
•
Data output rate can be set from 2.5 Hz to 7.5 kHz
•
Special operating modes (synchronous mode and multiple sampling)
