• Powerful 32-bit microprocessor system.
• Complete digital processing and control of measured values, from the sampling of
the analog input quantities to the initiation of outputs for, as an example, tripping or
closing circuit breakers or other switchgear devices.
• Total electrical separation between the processing stages of the 7SJ63 and the ex-
ternal transformer circuits, control circuits, and DC supply circuit because of the de-
sign of the binary inputs, outputs, and the DC converters.
• Complete set of functions necessary for the proper protection of lines, feeders, mo-
tors, and busbars.
• Additional protection and control functions available, some as options.
• Continuous calculation and display of measured quantities on the front of the de-
vice.
• Easy devise operation through an integrated operator panel or by means of a con-
nected personal computer running DIGSI
• Recording of event data, fault data, and waveform captures with SER information
to be used for analysis and troubleshooting.
• Communication with SCADA or substation controller equipment via serial interfaces
through the choice of data cable, modem, or optical fibers.
• Constant monitoring of the measurement quantities, as well as continuous self-di-
agnostics covering the hardware and software.
