72 489 GENERATOR MANAGEMENT RELAY – COMMUNICATIONS GUIDE
9. Analog input values may be –50000 to +50000 if so configured. Therefore, 32-bit
analog input capability is required to read the full possible range. If the SCADA
equipment can only read 16-bit registers, the analog inputs should be configured to
operate within the range –32768 to +32767.
10. Each neutral voltage quantity is available at two different points, with two different
scale factors (volts and tenths of a volt). The user should select the unit which is closest
to providing the resolution and range desired. If 32-bit analog input capability is
present, the higher-resolution (tenths of a volt) points should generally be used, since
they provide the greatest resolution.
