Mode of Operation
Transmitters with current sig-
nal input. The current signal
is converted into a binary
value represented as the bi-
nary status of an entire chan-
nel group (8 bit). This binary
value may be reconverted into
current or voltage signals
through receivers with ana-
logue outputs (type FAD 15..)
or displayed in a scaled 7-
segment display via D 6369
6475.
A signal change of 0.392% of
full scale influences the least
significant bit, which is the
highest channel of the se-
lected group (F8 if FMK F is
plugged in). A signal change
of 49.8% of full scale influ-
ences the most significant bit
or the lowest channel of the
selected group (F1 in the
above example).
No value is transmitted un-
less the transmission enable
input is activated (pins 5 and
7 connected). This input may
also be used to transmit up to
255 individual values on one
channel group by using Dup-
line receivers with demultiplex
output type D 1230 5111.
Note:
Analog transmitters
must not be used in systems
where channel generators
with 2 or 3 sequences are in-
stalled.
