Interference Frequency Suppression
The 2AI U High Feature and 2AI I 2/4WIRE High Feature analog input modules
support the interference frequency suppression setting (50 Hz or 60 Hz) for the
interface module. These High Feature analog input modules also allow you to
disable interference frequency suppression, thus ignoring the setting made on the
interface module. If you disable interference frequency suppression, the
conversion and cycle times become faster for these modules.
