The SD version of the 2400-A16 is a great way to achieve a stand-alone method for data logging. The station can be used as a 16 input
stand-alone logger, or as part of a SCADA data highway with backup logging facility.
The user friendly and free to download Intech Micro Station Programmer software (version 5.2.3613.5 or later), supports the reading of SD cards from the 2400-A16-SD.
