Isolated Digital I/O board
for PCI Express
DIO-3232L-PE
This product is a PCI Express bus-compliant interface board
that extends the digital signal I/O functions of a PC.
This product is a 12 - 24VDC opto-coupler isolated type with
opto-coupler isolated input 32 channels and opto-coupler
isolated open-collector output 32 channels. You can use 32
channels of input signals as interrupt inputs. Equipped with
the digital filter function and output transistor protection circuit
(surge voltage protection and overcurrent protection).
Windows/Linux driver is bundled with this product.
* Specifications, color and design of the products are subject to
change without notice.
Features
Opto-coupler bus isolation
As the PCI Express bus (PC) is isolated from the input and
output interfaces by opto-couplers, this product has excellent
noise performance.
You can use 32 channels of input signals as interrupt
events.
You can use 32 channels of input signals as interrupt events
and also disable or enable the interrupt in bit units and select
the interrupt edge.
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.
This product has a digital filter to prevent input signals
from carrying noise or a chattering.
This product has a digital filter to prevent input signals from
carrying noise or a chattering. All input terminals can be
added a digital filter, and the setting can be performed by
software.
Output circuits include zener diodes for surge voltage
protection and overcurrent protection circuit.
Zener diodes are connected to the output circuits to protect
against surge voltages. Similarly, overcurrent protection circuits
are fitted to each group of 8ch outputs.
The output rating is max. 35VDC, 100mA per ch.
Functions and connectors are compatible with PCI
compatible board PIO-32/32L(PCI)H.
The functions same with PCI compatible board
PIO-32/32L(PCI)H are provided.
In addition, as there is compatibility in terms of connector
shape and pin assignments, it is easy to migrate from the
existing system.
DIO-3232L-PE
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.

Connect the input signals to a device which can be
current-driven, such as a switch or transistor output device.
The connection requires an external power supply to feed
currents.
The board inputs the ON/OFF state of the current-driven device
as a digital value.

The rated output current per channel is 100 mA at maximum.
The output section can also be connected to a TTL level input
as it uses a low-saturated transistor for output. The residual
voltage (low-level voltage) between the collector and emitter
with the output on is 0.5 V or less at an output current within 50
mA or at most 1.0 V at an output current within 100 mA.
A zener diode is connected to the output transistor for
protection from surge voltages.
A PolySwitch-based
overcurrent protector is provided for every eight output
transistors. When the overcurrent protector works, the output
section of the board is temporarily disabled. If this is the case,
turn of the power to the PC and the external power supply and
wait for a few minutes, then turn them on back.
CAUTION
When the PC is turned on, all output are reset to OFF.

The input circuits of interface blocks of this product is illustrated
in the image above. The signal inputs are isolated by
opto-couplers (ready to accept current sinking output signals).
The board therefore requires an external power supply to drive
the inputs. The power requirement for each input pin is about
5.1 mA at 24 VDC (about 2.6 mA at 12 VDC).
