SM 1238 Energy meter module
The SM 1238 Energy Meter 480 V AC is designed for machine-level deployment in an S7-
1200 system. It records over 200 different electrical measurement and energy values. It lets
you create transparency about the energy requirements of individual components of a
production plant down to the machine level. Using the measured values provided by the SM
1238 Energy meter module, you can determine energy consumption and power demand.
For more information about this product and for the product documentation and
specifications, refer to the product catalog web site for the SM 1238 Energy meter module
