Scanner®2000 Expansion Board
QuickStart
Align hole in
expansion board
with stando.
Align pins on back
of expansion board
with black headers.
Part No. 9A-30165026, Rev. 03
The Scanner 2000 Expansion Board expands the
Scanner 2000’s input/output to include:
an additional turbine input
a pulse input (3-30 VDC or contact closure)
two analog inputs (1-5 V, 0-5 V, or 4-20 mA)
an analog output (4-20 mA)

Installation
Before installing the
expansion board,
remove all power from
the Scanner 2000
(battery and external
power). The expansion
board attaches to two
headers positioned
between the two large
terminal blocks on the
main board. Remove
wiring from the main
board if necessary to
guide the expansion
board into position.
Remove the stando
from packaging and
press it into the hole
near the center of the
main board until it
snaps into place.
Guide the expansion
board over the stand-
o and align the pins
on the under side
with the headers on
the main board.

2.
When the board is
positioned correctly,
text on both boards
should face the same
direction.
Gently press the
expansion board and
the main board
together until the
expansion board
snaps into place over
the stando.
3.
Restore wiring con-
nections to the main
board, reconnect the
MVT if disconnected,
and make eld wiring
connections to the
expansion board.
Restore power to the
Scanner 2000 and
reboot the Scanner to
allow detection of the
expansion board.

CAUTION: FAILURE TO ALIGN PINS AND HEADERS
CAN DAMAGE THE BOARDS.

Turbine Input 2
The Turbine Input 2
accepts a turbine
owmeter input signal
generated by a magnetic
pickup. The Scanner
2000 can be congured
to use this signal to
calculate and display
instantaneous ow rates
and accumulated totals.
Another turbine input
(Turbine Input 1) is pro-
vided on the main circuit
board. When the expan-
sion board is installed, a
dierential pressure ow
run and two turbine runs
can be monitored and
logged simultaneously.
Pulse Input
The pulse input provides
an optically isolated
input for high-amplitude
pulse (frequency) signals,
which includes signals
from a turbine meter
equipped with a
preamplier or signals
from a PD meter (via
contact closure).
The Scanner 2000 can
calculate ow from no
more than two pulse
(frequency) inputs at
a time. Therefore, a
pulse input can be used
simultaneously with only
one turbine input (main
board or expansion
board).

Inputs/Outputs
All inputs and outputs
are congured with
ModWorX™ Pro
software provided
with each Scanner
2000 microEFM.
Analog Inputs
The analog inputs, which
can be congured for a
1-5 V, 0-5 V or 4-20 mA
signal, can receive read-
ings from a pressure or
temperature sensor for
use in AGA-7 gas cal-
culations. Alternatively,
they can be used to log
measurements from any
device with a 1-5 V, 0-5 V
or 4-20 mA output.
Transmitter power is
provided by the Scanner
only when the Scanner is
externally powered. The
output voltage equals
the input voltage less
0.25 VDC, and is limited
to 20 mA.
If a 4-20 mA transmitter
is used, a resistor must
be added to the circuit.
The expansion board
circuit will support a
resistor range of 200 to
300 ohms; 250 ohms is
recommended.

Analog Output
(4-20 mA)
The 4-20 mA linear
current output can be
congured with
ModWorX™ Pro
software to represent
any parameter in the
holding registers. This
output requires a two-
conductor cable to be
connected to an 8 to 30
VDC power supply (volt-
age required is depen-
dent on loop resistance)
and an analog readout
device to be located in
the remote location.
The graph above shows
the minimum voltage
For example, if a power
supply voltage of 24
volts is available to
power the current loop,
the maximum load
resistance would be 800
ohms.
