change without notice.
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 16ch and opto-coupler isolated
open-collector output 16ch. You can use all of the 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.
Possible to be used as a data recording device for LabVIEW,
with dedicated libraries.
Opto-coupler isolated input (supporting current sink
output) and opto-coupler isolated open-collector output
(current sink type)
This product has the opto-coupler isolated input 16ch
(supporting current sink output) whose response speed is
200sec and opto-coupler isolated open-collector output 16ch
(current sink type).
Common terminal provided per 16ch, capable of supporting a
different external power supply Supporting driver voltages of 12
- 24 VDC for I/O
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 all of the input signals as interrupt events.
You can use all of the 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.
Functions and connectors are compatible with PCI
compatible board PIO-16/16L(PCI)H.
The functions same with PCI compatible board
PIO-16/16L(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.
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.

This pin is left unconnected.
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.

as a digital value.

* I-xx represents the input pin.
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 5.1mAat 24VDC
(about 2.6mA at 12VDC).

* O-xx represents the output pin.
The output circuits of interface blocks of this product is
illustrated in the image above. The signal output section is an
opto-coupler isolated, open-collector output (current sink type).
Driving the output section requires an external power supply.
The rated output current per channel is 100mA 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 0.5V or less at an output current within
50mA or at most 1.0V at an output current within 100mA.
A zener diode is connected to the output transistor for
protection from surge voltages. A PolySwitch-based
overcurrent protector is provided for every 8 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.
