-
Corrosive Industrial Environments: Wastewater treatment, pulp & paper mills, and chemical plants with G3-rated conditions.
Engineering FAQ
What is the benefit of channel-to-channel isolation?
-
Prevents electromagnetic interference or ground potential differences in one sensor from affecting others, ensuring accurate readings across all 16 channels.
Does the AAR145-S00 S1 support hot-swapping?
-
Yes. In a dual-redundant I/O nest, the module can be replaced while the system remains energized, without data interruption.
How does the G3 option affect module lifespan?
-
The G3 conformal coating protects the PCB from corrosive gases such as H₂S and Cl₂, extending the operational life in harsh industrial environments.
