Contec DIO-128SLX-USB Quick Start Manual

Bi-Directional Digital I/O Unit with
Opto-Isolation for USB
DIO-128SLX-USB
* Specifications, color and design of the products are subject to change
without notice.
Features
- Bidirectional signal control is possible, because digital input
point and a digital output point are common.
The I/O pin can use as an input pin or an output pin without changing
the wire connection.
- 128 channels of Optocoupler isolated inputs (compatible with
current sink output) and 128 channels of Optocoupler
isolated open-collector outputs (current sink type)
This product has the 128 channels of Optocoupler isolated inputs
(compatible with current sink output) and the 128 channels of
Optocoupler isolated open-collector outputs (current sink type) whose
response speed is 200µsec. Supporting driver voltages of 24 VDC for
I/O. (24VDC external circuit power supply is required separately.)
- Compatible to USB1.1/USB2.0
Compatible to USB1.1/USB2.0 and capable to achieve high speed
transfer at HighSpeed (480 Mbps).
- USB HUB function
This product has the USB HUB function. Max. 4 DIO-128SLX-USB can
be used in 1 USB port of PC. *3
128SLX-USB, you can do by connecting DIO-128SLX-USB to the
another USB port of PC side.
Also, you can connect the CONTEC's USB device other than DIO-
6464LX-USB to the USB port of DIO-6464LX-USB. *1*2
- Common terminal provided per 16 channels
Compatible with Common terminal provided per 16 channels, capable
of supporting a different external power supply.
- Optocoupler bus isolation
As the USB (PC) is isolated from the input and output interfaces by
Optocouplers, this product has excellent noise performance.
- You can use 16 input signals as interrupt request signals.
You can use 16 input signals as interrupt request signals and also
disable or enable the interrupt in bit units and select the edge of the
input signals, at which to generate an interrupt.

This product is an USB2.0-compliant digital I/O unit used to provide a
digital signal I/O function on a PC.
This product features 128 channels of Optocoupler isolated inputs
(compatible with current sink output) and 128 channels of Optocoupler
isolated open-collector outputs (current sink type). The input point and
the output point are common. Therefore each I/O pin can use as an
input pin or an output pin. 24VDC external circuit power supply is
required to drive a photo coupler . You can use 16 input signals as
interrupt request signals. Equipped with the digital filter function and
output transistor protection circuit (overcurrent protection).
Windows driver is bundled with this product. Possible to be used as a
data recording device for LabVIEW , with dedicated libraries.

- This product has a digital filter to prevent wrong recognition
of input signals from carrying noise or a chattering.
This product has a digital filter to prevent wrong recognition of 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 overcurrent protection circuit.
Overcurrent protection circuits are fitted to each group of 8ch outputs.
The output rating is max. 24VDC, 100mA per channel.
- Windows compatible driver libraries are attached.
Using the attached driver libraries API-USBP (WDM) makes it possible
to create applications of Windows. In addition, a diagnostic program
by which the operations of hardware can be checked is provided.
- LabVIEW is supported by a plug-in of dedicated library VI-
DAQ.
Using the dedicated library VI-DAQ makes it possible to make a
LabVIEW application.
*1 Do not connect the device other than that of CONTEC's USB to the USB port included on the
DIO-128SLX-USB. Otherwise, this may cause a failure or malfunction.
*2 When connecting multiple units with USB HUB function and set up them, do one at a time and
complete setup for the previous unit before starting to do the next unit.
*3 This product cannot be stacked up for installation.
