SMC 133 is specially designed for remote monitoring of energy
consumption and its quality. The DIN rail display-less
design is suitable for a wide spectrum of tasks in substations
and similar high demanding applications. Absence of local
panel controls (display and keyboard) limits possibilities for
hostile user interaction.
This instruments are an ideal source of data for any modern
SCADA system with embedded support for ModBus protocol
and it is also supported by our free ENVIS application. Its
input and output set can be extended with additional IO modules
for advanced control functionality.
SMC 133 features large internal memory for data logging of
measured values. Quantities include a multitude of additional
functions such as the storage of minimum, average and maximum values, energy consumption, logs of state
changes and many other. All this information is available for later download by the supervising software.
