Hardware and software is provided to generate DCmA signals that allow interfacing with external equipment. Specific hard-
ware details are contained in chapter 3. The DCmA output channels are arranged in a manner similar to transducer input or
CT and VT channels. The user configures individual channels with the settings shown below.
The channels are arranged in sub-modules of two channels, numbered 1 through 8 from top to bottom. On power-up, the
relay automatically generates configuration settings for every channel, based on the order code, in the same manner used
for CTs and VTs. Each channel is assigned a slot letter followed by the row number, 1 through 8 inclusive, which is used as
the channel number.
Both the output range and a signal driving a given output are user-programmable via the following settings menu (an exam-
ple for channel M5 is shown).
The relay checks the driving signal (
x
in equations below) for the minimum and maximum limits, and subsequently re-
scales so the limits defined as
MIN VAL
and
MAX VAL
match the output range of the hardware defined as
RANGE
. The follow-
ing equation is applied:
(EQ 5.37)
where:
x
is a driving signal specified by the
SOURCE
setting
I
min
and
I
max
are defined by the
RANGE
setting
k
is a scaling constant calculated as:
(EQ 5.38)
The feature is intentionally inhibited if the
MAX VAL
and
MIN VAL
settings are entered incorrectly, e.g. when
MAX VAL
–
MIN
VAL
< 0.1 pu. The resulting characteristic is illustrated in the following figure.
