USB ANALOG/DIGITAL
MULTI I/O-CARD OUT8-IN8-AD4-DA
The analog output signal is scaled on 0... 2.5 V
and is available over an operation amplifier
buffered at the output. Here also, a simple test is
possible: The light intensity of LED changes
proportional to the consumed voltage.
The standard rail housing of the card can be
directly installed in the switchgear cabinets. The
connection is through the USB-Port of PC (USB1.1
specification, 2.0 compatible).
Safety instructions
The product should be installed
and used only according to the
intended application.
The I/O card may also contain
voltage over 24 V depending on the external
circuit involved. Contact with live voltage parts
leads to fatal dangers. Therefore, fitment and
maintenance of the card shall be carried out by
only trained personnel. The USB card must be
assembled inside a switchgear cabinet or in a
fully closed plastic housing. Mounting and
servicing operations should be carried out only
after switching off the voltage.
Touching the electronic components in
switched off condition should also be avoided.
Electronic components can get damaged due
to electrostatic discharge process.
The product is not meant for controlling
electrical systems which perform safety related
functions. In normal operation also, there is
always a danger of malfunctioning due to any
fault or failure of the control system itself (PC)
or e.g. due to any inherent software error of the
control program. The user has to ensure that
there are no consequential damages due to
malfunctioning or undefined switching status
of the relay. This is all the more possible, if
heavy loads like heaters or motors are
triggered.
Due to wrong tightening of screws of the
connection terminals or by use of
inappropriate tool, the terminals can get
damaged because of which the insulation or
the contact can get disturbed. Badly connected
leads can come out during operation and
cause a serious risk to safety. Due to contact
resistance at terminal connections, there can
be increased heat generation which can cause
fire. Wrongly wired connections can destroy
electric components and cause other damages.
Accessories
As accessories, a matching USB connection cable
and also a power supply unit (Standard
12V/630mA) are available. For safe operation, the
PCB should be placed in a suitable housing (e.g.
Ordering No. GEH-REL). The I/O module is
compatible with the software "Profilab" with which
regulation and control programs can be created
under graphical environment without any
programming knowledge.
Installation
System requirements: Operating system
Windows 98, 2000 or XP. USB-connection 1.1 or
higher, CDROM-drive, 64 MB RAM (XP: 128 MB),
minimum 2 MB free hard disk space.
For a first test of the card, the input and output
terminals can be left unwired, as the I/O status is
also indicated over the LEDs and the input can be
set over the switch. The current supply of the USB
part is through the interface and supply to the
outputs is from the external power supply unit.
The integration to a PC is over a standard
connection cable directly to the PC. The USB
connection corresponds to specification 1.1 and is
compatible to 2.0.
During first time connection to the PC, the
standard windows dialogue box starts for driver
installation. Install the required device driver, by
manually selecting the device driver in the
Hardware assistant. The driver files are on the CD
in the folder "\Driver\EZUSB\Driver_XP_2K" (for
Windows 98, it is in the directory Driver_98).
After this, install the software USB-Tools. This is
on the CD under the directory
“\Software\USB\USB-Tools“. This software is
required for testing the card and setting the card
number.
Now start the software USB-Tools. In the
application window, the connected I/O card with
the description “OUT8-IN8-AD4-DA” and card
number appears. By double clicking on the device
description, a window opens up in which you can
test and also configure various functions of the
card.
Settings
Card number: If you are operating only one card
on the PC, then you don't need to do any settings
for this.
However, up to 32 USB-cards can be operated on
a PC. For operating multiple cards, a unique card
number must be assigned to each card. For this,
the card is to be connected to the PC and the write
protection jumper connection WP is to be closed
with a shorting plug. The assigning of new card
address is done with the corresponding dialogue
box in the window of USB-TOOLS.
