Introduction 1
PCIe-7432
1 Introduction
ADLINK'S PCIe-7432 for PCIe bus provides 32CH isolated DI and
32CH isolated DO and robust 2,500V isolation protection, suitable
for most industrial applications.
All digital input channels are identical non-polar and opto-isolated.
All channels are isolated and suitable for collecting digital inputs in
noisy environments. Digital input channel 0 & 1 interrupt are sup-
ported.
Common input junction can be common ground or common
power, depending on the environment, such that digital input can
be either current source or current sink. When isolated digital out-
put is ON, sink current is through transistors, and when OFF, none
is.
The extra connection is utilized for the flywheel diode, forming a
current-release closed loop, whereby transistors are protected
from high reverse voltage generated by the inductance load when
output is switched from ON to OFF.

1.7 DI/O Channels
Isolated Digital Input Channels
Isolated digital input has an open collector transistor structure with
voltage range 0V to 24V and input resistance of 2.4kΩ. Connec-
tion between external signals and the PCIe-7432 is as shown in
Fig A01. Since input common junction can be common ground in
the environment, digital input can be either a current source or a
current sink.

Figure 1-3: Isolated Input Connection
Isolated Digital Output Channels
Common ground connection of the isolated digital output is as
shown. When isolated digital output is ON, sink current is through
transistors, and when OFF, none is. When the load is of an induc-
tance nature, such as a relay, coil or motor, the VDD pin must be
connected to an external power source. The extra connection is
utilized for the flywheel diode to form a current-release closed
loop, whereby transistors are protected from any high reverse volt-
age generated by the inductance load when output is switched
from ON to OFF.

2 Getting Started
2.1 Unpacking Checklist
Before unpacking, check the shipping carton for any damage. If
the shipping carton and/or contents are damaged, inform your
dealer immediately. Retain the shipping carton and packing mate-
rials for inspection. Obtain authorization from your dealer before
returning any product to ADLINK. Ensure that the following items
are included in the package.
XPCIe-7432 high-speed DI/O card
XQuick Start Guide
If any of the items is damaged or missing, contact your dealer
immediately.
2.2 Installing the Card
Install the card driver before you install the card into your com-
puter system. See “Software Support” on page 3. for driver sup-
port information.
To install the card:
1. Turn off the system/chassis and disconnect the power
plug from the power source.
2. Remove the system/chassis cover.
3. Select the PCIE Express slot that you intend to use, then
remove the bracket opposite the slot, if any.
4. Align the card connectors (golden fingers) with the slot,
then press the card firmly until the card is completely
seated on the slot.
5. Secure the card to the chassis with a screw.
CAUTION:
The card must be protected from static discharge and physical
shock. Never remove any of the socketed parts except at a
static-free workstation. Use the anti-static bag shipped with the
product to handle the card. Wear a grounded wrist strap when
servicing.

10 Getting Started
6. Replace the system/chassis cover.
7. Connect the power plug to a power source, then turn on
the system.
Configuration
All PCI/PCIE Express cards on your system are configured individ-
ually. Because configuration is controlled by the system and the
software, no jumper setting is required for base address, DMA,
and interrupt IRQ. Configuration is subject to change with every
boot of the system as new PCI/PCIE Express®cards are added or
removed.
Troubleshooting
If your system fails to boot or if you experience erratic operation
with your PCI/PCIE Express card in place, an interrupt conflict
may have been generated (such as when the BIOS Setup is incor-
rectly configured). Refer to the system’s BIOS documentation for
details.
