The S7-1200 product portfolio has been extended by an additional Signal module to measure energy data. The SM1238 Energy Meter 480VAC is an additional signal module type and 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.
The SM1238 Energy Meter provides measurement of electrical variables from single-phase, two-phase and three-phase AC power supply networks – with a maximum nominal voltage between two outer conductors 480 VAC (max. phase voltage 277 VAC).
The meter provides recordings of:
- Phase angles
- Energy / electrical work
- Minimum and maximum values
- Power factors
- Operating hours
- Energy usage counter
Finally, the module supports the following functions:
- Firmware update
- I&M identification data, Reconfiguration in RUN, Diagnostics interrupts
