The S-FS-TRMSA is easy-to-configure, True-RMS input measurement modules. The S-FS-TRMSA is compatible with HOBO® H22 series data loggers. The 2-channel modules have an input range of 512 millivolts RMS full-scale. Thus, they are fully compatible with industry-standard voltage and current transformers (PT and CT) which output 333 millivolts RMS full-scale. The modules feature extremely low-power operation, resulting in long battery life for unattended data logging applications.
