Analog Output Settings
The SEL-701 Relay provides a dc analog current output with three signal ranges
and a variety of output parameters. Set the Analog Output Signal Type to select the
operating range of dc output current. Select the Analog Output Parameter from the list
of available options.
When you select a percentage-type output parameter, the relay automatically
scales the output to indicate full scale at 100%. If you select a hottest RTD output
parameter, the relay automatically scales the output to indicate full scale at 250°C or
482°F and zero scale at 0°C or 32°F. If you select average or maximum phase current
output parameters, the relay requests that you enter your preferred Analog Output Full
Scale Current in secondary amps. The range available depends on whether your
nominal secondary current is 5 A or 1 A. The Analog Output Full Scale Current setting
is hidden when the Analog Output Parameter is not AVG_I or MAX_I.
