S-DIAS Strain Gauge Input Module AI 022-1
with 2 analog inputs
The S-DIAS AI 022-1 strain gauge input module is used to analyze meas-
uring bridges (i.e. strain gauge load cells)
.
With a 24-bit resolution, meas-
urement values are provided with an overall accuracy of 0.035 %.
The AI 022-1 differs from the AI 022 in the following technical data:
- the resolution of the measurement range is increased to a max-
imum of 100 %, the reduction in the expanded measurement
range of 100-150 % for evaluating overstretching of the load cell
by 50 % was eliminated.
- For increased noise suppression, the hardware input filter has a
lower limiting frequency of 8 Hz instead of 180 Hz.
- the support of lower impedance load cells (e.g. via the parallel
connection of several load cells)
– loads of at least 60 Ω / chan-
nel from the AI 022-1 are now supported; lower load cell loads
lead to a higher current consumption of the module on the
S-DIAS bus
