1DEFINITION OF APPLICATION
1.1 Intended use
The board APCI-7xxx-3F0F1Fmust be inserted in a PC with PCI 5V/32 bit (PCI
3.3V/32 Bit) which is used as electrical equipment for measurement, control and
laboratory pursuant to the norm EN 61010-1 (IEC 61010-1). The used personal
computer (PC) must fulfil the requirements of IEC 60950-1 or EN 60950-1 and
55022 or IEC/CISPR 22 and EN 55024 or IEC/CISPR 24.
The use of the board APCI-7xxx-3 in combination with external screw terminal
panels requires correct installation according to IEC 60439-1 or EN 60439-1
(switch cabinet / switch box).
1.2 Usage restrictions
The APCI-7xxx-3 board must not to be used as safety related part (SRP).
The board must not be used for safety related functions, for example for
emergency stop functions.
The APCI-7xxx-3 board must not be used in potentially explosive atmospheres.
The APCI-7xxx-3 board must not be used as electrical equipment according to
the Low Voltage Directive 2006/95/EC.
1.3 General description of the board
The board APCI-7xxx-3 provides the personal computer (PC) with 1-port, 2-port,
4-port or 8-port asynchronous serial interface for the communication with external
devices:
Board Interface
APCI-7300-3 1-port
APCI-7420-3 2-port
APCI-7500-3,
APCI-7500-3/4C
4-port
APCI-7800-3 8-port
The operating mode of the interface depends on the MX modules installed.
The board is to be connected to the peripheral through a shielded cable, which
shielding should be grounded on both ends.
1Common designation in the manual for the boards APCI-7300-3, APCI-7420-3, APCI-7500-3,
APCI-7500-3/4C and APCI-7800-3

APCI-7xxx-3 Figures and Tables
10
Minimum specifications of the connection cable:
- metallized plastic hoods
- shielded cable
- cable shield folded back and firmly screwed to the connector housing.
The board supports serial communication through 1, 2 or 4 asynchronous serial
ports. The use of the board depends on the following parameters (See table
below).

If the basic board APCI-7xxx-3 is used with optically isolated modules and non
isolated modules, then the safety built by the creeping distance of 3.2 mm is not
ensured for the non isolated modules.
The use of the board in a PC could change the PC features regarding noise
emission and immunity. Increased noise emission or decreased noise immunity
could result in the system not being conform anymore.
Check the shielding capacity of the PC housing and cable prior to putting the
device into operation.
The use of the board includes observing all advises given in this manual and in the
safety leaflet.
1MXxxx-G: E.g. PM232-G: Module for the operating mode RS 232 with option G (optical
isolation)
MXTTY: Module for 20 mA constant loop. As standard it is optically isolated.
2The max. lengths are for standard interface cables

APCI-7xxx-3 Figures and Tables
12
Uses beyond these specifications are not allowed. The manufacturer is not liable
for any damages which would result from the non-observance of this clause.
Make sure that the board remains in the protective blister pack
until it is used.
For all operating modes, the signal lines are to be twisted in pairs with GND.
Use exclusively connection cable with twisted pairs.
The housing of the peripheral connector
-is to be firmly screwed together with the shield of the cable.
-is to assure a low-resistance connection (< 100 mΩ) between the shield and the
housing of the PC.
The shield of the cable is to be earthed on both ends.
Do not remove or alter the identification numbers of the board.
If you do, the guarantee expires.
