Identifying letters
The following table lists the identifying letters for the 8 or 16 functions of
the solid-state multifunctional 3RP15 05 time relay:
The
•
after the identifying letter indicates that the second changeover con-
tact present reacts as an immediate switching contact (controlled by the
supply voltage or the start contact depending on the function). If this
•
is not
present, the second changeover contact reacts with a time delay like the
first changeover contact.
