Isolated Analog Output Board for PCI
AO-1604CI3-PCI
* Specifications, color and design of the products are subject to change
without notice.
This product is a PCI bus supported board that extends the analog signal
output functions of a PC. Equipped with four channels of 16-bit analog
output, the product is an individual isolation model using a D/A
converter for each channel to provide isolation for the bus line with PC
and between channels. The voltage/current output range (voltage :
±10V, 0 - +10V; current : 0 - 20mA) can be set by jumper for each
channel. This product can generate signals that are synchronized with
the internal timer or an external clock. Windows/Linux driver is bundled
with this product.
Using the dedicated library VI-DAQ makes it possible to create each
application for LabVIEW.
Features
Analog output 4ch, 16bit-resolution, conversion speed 20µsec
This product has the Analog output (4ch, 16bit, 20µsec).
Additionally, the voltage/current output range (voltage : ±10V, 0 - +10V,
current : 0 - 20mA) can be set by jumper for each channel.
PC bus line, opto-coupler isolation between channels
The opto-couplers mounted for each channel provide electric isolation
between channels as well as between the inside of the board (PC) and
output pins.
Simultaneous output of voltage to a specified channel or all channels
This product can generate output voltage either for a specified channel
only or for all of the channels simultaneously. This can be selected or set
by software.
Windows/Linux compatible driver libraries are attached.
Using the attached driver library API-PAC(W32) makes it possible to
create applications of Windows/Linux. In addition, a diagnostic
program by which the operations of hardware can be checked is
provided.
Control of sampling start/stop can be selected by an external trigger
or other factor
Control of sampling start can be selected by software or an external
trigger. Control of sampling start and control of sampling stop are
independent from each other; therefore, they can be set separately.
Control of sampling stop can be selected by completion of a specified
number of sessions or an external trigger. In addition, when an error
occurs, sampling is stopped, regardless of the settings for sampling stop
conditions.
A sampling cycle can be selected from the internal clock (high precision
timer mounted on the board) or an external clock (control signal entered
from outside).
Relay provided to control output voltage
The mounted relay prevents unstable output voltage from being
generated upon power-up. This protects the connected devices from
damage and malfunction, as the output voltage for all the channels is
generated via the relay.
LabVIEW is supported by a plug-in of dedicated library VI-DAQ
Using the dedicated library VI-DAQ makes it possible to create each
application for LabVIEW.

▼CAUTION
Do not connect any of the outputs and power outputs to the analog or digital ground.
Neither connect outputs to each other. Doing either can result in a fault.
Analog Output Signal Connection
The sections below describe how to connect the signals using flat cable
and shielded cable.
Connecting example of voltage output
The following figure shows an example of optional flat cable (PCA37P)
connection. Connect the CN1 analog output channels and ground to the
external device's input and ground.
Connection of voltage output (Flat Cable)
The following example connects a signal source to the board using a
shielded cable. Use shielded cable if the distance between the board
and loading is long or if you want to provide better protection from
noise. Use the core of the shielded cable to connect the analog output
of CN1 to the input of the external device and use the shield braid to
connect the CN1's analog ground to the external device's ground.
Analog Output Connection (Shield Cable)
▼CAUTION
- If the board and the target receive noise or the distance between the board and the signal source is too long,
data may not be input properly.
- The maximum output current-carrying capacity of the analog output signal is ±5 mA. Check the
specifications of the target before connecting the board to it.

- Do not connect any of the outputs and power outputs to the analog or digital ground.
- Do not connect the analog output signal to the other analog output signal and output signal of external
device. Doing so may malfunction.
- Do not plug or unplug the interface connector to or from while the PC or external device power is turned on.
Doing so may malfunction.
- The DA converter may cause glitches as it contains no deglitcher.
Connecting example of current output
The figure below shows an example connection using a flat cable as the
optional one (PCA37P).
The load register is connected. Please adjust the register load RL
connected with the current output of each channel to 500 or less
including the resistance of wiring.
Each current output of CN1 and analog ground is connected to the
resister load RL.
Current output connection (Flat cable)
The following figure shows an example of shielded cable connection.
Use shielded cable if the distance between the loading and board is long
or if you want to provide better protection from noise. Connect the
each current output of CN1 to the register load in the core wire of
shielded cable and connect the each analog ground of CN1 to the
register load in the shielding of shielded cable.
Current output connection (Shielded cable)
▼CAUTION
- Do not short the output signals to analog ground, digital ground, and/or power line. Doing so may damage
the board.
- If connected to each output, a pull-up resistor must be about 10 k to pull up with a 3.3V power source.
- Each input accepts 5V TTL signals.
Control signals Connection
Input signals connection
To the “External Sampling Clock Input” and “External Start Trigger Input”,
connect current driven devices such as a switch and a transistor output
device. Input circuit is as follows. An external power supply is required
to drive the input circuit. The power capacity required at this time is
about 11 mA per input channel at 24 VDC (or about 5.5 mA at 12 VDC).

Output signals connection
To the “Timer Output “ and “Settling Busy Output”, connect a relay
controller or a current driven control device such as a LED. Output circuit
is as follows.
An external power supply is required to drive the output circuit. The rated
output current is up to 50 mA per channel. The output transistor is not
associated with a surge voltage protection circuit. When the output
signal is used to drive the inductive load to a relay or lamp, apply surge
protection to the load side.
