G 3429 6470
Wiring Diagram
Mode of Operation
The G3429 6470 is a univer-
sal analog input module with
4 inputs. Each input can be
configured individually to
current or voltage measure-
ment. The transmission for-
mat is selectable and sup-
ports all Dupline®analog pro-
tocols Analink, 8-Bit or 3 1/2
digit BCD. Coding of the
module is solely done by dip-
and rotary-switches located
on the module, so the GAP
1605 programmer is not
needed.
With reference to the dia-
gram on the previous page,
the setting of the module
should be performed in the
following way:
Please note that no signals
must be applied to the inputs
before the correct mode
(current or voltage) is select-
ed by
means of the 4 shunt
switch
es on the top of the
system.
Set the range of each input
(0/4-20 mA or 0/2-10 V) by
means of the switches 1-4
on the front of the module,
and select the actual number
of inputs used with switches
5 and 6.
The module only take up
Dupline®addresses ac-
cording to the number of
enabled inputs, and the select
-
ed transmission protocol
(mode) set by switches 7 and
8.
Address allocation for the
Analink protocol:
If all four inputs are enabled,
the module will use four
Dupline®channels in consec-
utive order, starting from the
address set on the two rotary
switches on the front of the
unit.
Example: Setting of “D7”
means that input 1 transmits
on Dupline®channel D7,
input 2 transmits on D8,
input 3 transmits on E1 and
input 4 transmits on E2.
Address allocation for the
8-bit binary protocol:
If all four inputs are enabled
and non multiplexed mode is
selected (switch 9), the mo-
dule will use four Dupline®
channel groups (32 channels)
in consecutive order, starting
from the group set on the
first rotary switch (A-P). The
second rotary switch (0-F) is
not used in this mode.
Example: Setting of “F” on
the first rotary switch means
that input 1 transmits on
Dupline®group F, input 2
transmits on G, input 3 trans-
mit on H and input 4 trans-
mits on I.
If multiplexed mode is select-
ed the module will use one
Dupline®channel group (8
channels). The first rotary
switch (A-P) is used to set
the group and the second
rotary switch (0-F) to set the
multiplex address to be used
by the first input, no. 1.
Example: Setting of “F” on
the first rotary switch and “0”
on the second, means that
input 1 transmits on Dupline®
group F mux. adr. 0, input 2
transmits on F mux. adr. 1,
input 3 transmits on F mux.
adr. 2 and input 4 transmits
on F mux. adr. 3.
Address allocation for the 3
1/2 digit BCD protocol:
If all four inputs are enabled
and non-multiplexed mode is
selected (switch 9) the mo-
dule will use four Dupline®
channel group-pairs (64
channels) in consecutive
order. The first rotary switch
(A-P) is used to set the start
group pair. The second rotary
switch (0-F) has no function
in this mode.
Example: Setting of “C” or
”D” on the first rotary switch
means that input 1 transmits
on Dupline® group-pair C-D,
input 2 transmits on E-F,
input 3 transmits on G-H and
input 4 transmits on I-J.
If multiplexed mode is select-
ed the module will use one
Dupline®channel group-pair
(16 channels). The first rotary
switch (A-P) is used to set
the group-pair and the
second rotary switch (0-F) to
set the multiplex address to
be used by the first input, no.
1.
Example: Setting of “C” or
”D” on the first rotary switch
and “8” on the second,
means that input 1 transmits
on Dupline® group-pair C-D
mux. adr. 8, input 2 transmits
on C-D mux. adr. 9, input 3
transmits on C-D mux. adr. A
and input 4 transmits on C-D
mux. adr. B.
Note
The selected transmission
protocol is valid for all
enabled inputs. The module
can not transmit different
protocols at the same time.
Analog transmitters must not
be used in systems where
channel generators with 2 or
3 sequences are installed.
