Wiring Diagram
Transmitter with voltage sig-
nal input. The voltage signal
is converted into a binary
value represented as the bi-
nary status of an entire
channel group (8 bit). This
binary value may be recon-
verted into current or volta-
ge signals through receivers
with analogue outputs (type
FAD 15..) or displayed as 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
selected group (J8 if FMK J
is plugged in). A signal
change of 49.8% of full sca-
le influences the most sig-
nificant bit or the lowest
channel of the selected gro-
up (J1 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 trans-
mit up to 255 individual
values on one channel gro-
up by using Dupline recei-
vers with demultiplex output
type D 1230 5111.
The 10 VDC reference out-
put (pins 8 and 7) is a useful
feature to supply for instan-
ce a potentiometer whose
signal may represent physi-
cal parameters, e.g. shutter
position, opening angle etc.
Note: Analog transmitters
must not be used in systems
where channel generators
with 2 or 3 sequences are
installed.
