1. Safety Instructions
ThisinstrumentisproducedinaccordancewithClassIIofIEC348andVDE0411.
When delivered the intrument has been tested to meet all functions described.
Before installing the instrument please read the mounting and servicing instruc-
tions. We have no liability or responsibility to customer or any other person or
entity with respect to any liablity, loss or damage caused or alleged to be caused
directly or indirectly by equipment or software sold or furnished by us. Read the
installation instruction carefully. No liability will be assumed for any damage
caused by improper installation.
Inspect the instrument module carton for obvious damage. Be shurethereare no
shipping and handling damages on the module before processing. Do not apply
power to the instrument if it has damaged.
The warranty does not apply to defects resulting from action of buyer, such as
mishandling, improper interfacing, operation outside of design limits, improper
repair or unauthorized modifications.

3. General
The board IO 1388 was designed to interface with the PCs internal PCI-BUS
through any available expansion slot. Ther are 2 different models available:
• model IO 1388 / 0 - supplied with 16 / 16 input / output channels
• model IO 1388 / 1 - supplied with 32 /32 input / output channels
All input and output channels are optically isolated. In addition input and output
voltage levels of 24 V are also available. By this reason all input and output
channels can directly connected to a PLC.
Theoutput channelsareshortcircuitprotected.Eachchannelcanswitchcurrents
up to 1 A.
A watchdog is implemented. In a programmable register a distinct output channel
masc configuration can be programmed. If the watchdog timeout time is over, the
output channels are set to the predetermined state.
By an interrupt-enable-register the input channels can be programmed to gene-
rate interrupts. The interrupts can be generated by a positive-edge or a negati-
ve-edge trigger.
In addition there is a timer implemented. The timer e. g. can be used for reading
input channels in distinct intervals.
4. Function
The IO 1388 will use one PCI-slot within the pc. Because the PCI-bus supports
plugandplay,there arenojumpersorswitches tochangeconfiguration.Thecard
will use 8 x 32-bit-IO-addresses for the functions and 16 x 32-bit-IO-adresses for
the PCI-target-controller. You can use any number of IO 1388 within one pc
(depends on number of PCI-slots). The standard drivers supports up to 4 cards.
If more than 4 cards should be used, you can ask for a driver for more cards. The
card has one 37-pin SUB-D male connector for the input and output channels.
The functions of the card will be handled in a FPGA. This free
programabledevicemakesitpossibletosupportcustomerspecific
functions without changing the hardware. It is possible to imple-
ment additional special functions or fast controllers within the
FPGA.

6. Hints against noisy environment
All inputs and outputs are protected against noisy environment and high voltage
spikes. Nevertheless the location should be selected to ensure that no capacitive
or inductive interference can have aneffect on theinstrument or connectionlines.
It is advisable:
• To use shielded, twisted pair cables.
• The wiring of shields and ground (0V) should be star-shaped.
• Thedistance to interference sources shouldbeasfar as possible.
If necessary, protective screen or metal enclosures must be
provided.
• Coils of relays must be supplied with filters.
• Parallel wiring of input signals and AC power lines should be
avoided.

7. Installation
The installation of the card should only be done by qualified personal
only.Before installationallcomponentshaveto be disconnectedfrom
power supply. Because within PC’s and the peripherals are high
voltages it is dangerous to life!
7.1. Hardware configuration
The IO 1388 uses plug and play and so there is no need for any settings.
