< Output items>
Table 5.5-3 Output items of PWS
Used to output
that relay is in
fail status.
N/C contact is used for output.
Note)
This contact will close when relay is
in fail status or DC voltage is off.
N/O contact is used for output.
Note)
This contact will open when relay is
in fail status or DC voltage is off.
Same as N/C contact of FAIL1
Same as N/O contact of FAIL1

As shown in Table 5.5-4, there are differences between the IED case structures “Type using
compression terminals” and “Type using ring terminals”.
