The Maximum Power Consumption has been increased by 10% over the value calculated with the currents shown to
take into account higher allowed values of the crate or PCI voltages.
The U1071A-FAMILY can use the PCI Bus at frequencies up to 66 MHz. All other 8-bit Acqiris digitizers use the
PCI Bus at 33 MHz only. All modules are compatible for either V I/O = 3.3 V or 5 V.

Environmental and Physical
The U1071A-FAMILY modules have a Declaration of Conformity according to EN ISO/IEC 17050-1:2004 and the
EMC Directive 2004/108/EC and carry the CE Marks of Compliance. This Declaration can be viewed at
r modules have a Declaration of Conformity according to EN ISO/IEC 17050-
1:2004 and the EMC Directive 2004/108/EC and carry the CE Marks of Compliance.
The front panels of the CompactPCI modules are in compliance with the IEEE 1101.10 standard.
Operating Temperature
0° to 40°C – for the DC271-FAMILY modules
0° to 50°C – all other modules
For the DCxxx compactPCI modules the above values are for the ambient temperature of the room (or equivalent)
where the CompactPCI crate is located. For DPxxx PCI modules, located in a PC (or equivalent), it is the cooling air
temperature inside the box that is of interest. This can be significantly higher than the ambient air temperature of the
room. In both cases the temperature as measured on the board may well be significantly higher. On-board
temperatures above 60°C should be avoided. If a PCI module indicates a temperature > 60°C ventilation should be
added or improved if possible.
Relative Humidity
5 to 95% (non-condensing)
Dimensions
All DP modules conform to the PCI standard. The DP214/DP235/DP240 and DP211/DP212/DP111 modules are 107
mm
× 210 mm and require a long card slot. If used with the XP103 fan they can be adjusted to conform to the full
342 mm length. The U1071A-FAMILY measures 107 mm
× 170 mm without its fan. If used with the XP104 fan it
can be adjusted to conform to the full long card length of 342 mm; when the XP105 fan is used the overall length is
235 mm. All other cards require a short card slot (107 mm
× 175 mm). An XP100 fan will add 45 mm to the length
of any card.
The DC110, DC135, DC135HZ, DC140, and DC140HZ conform to the 3U CompactPCI standard (100 mm
× 160
mm
× 20 mm). All other DC modules conform to the 6U CompactPCI standard (233 mm × 160 mm × 20 mm).
Safety
Complies with EN61010-1
EMC Immunity & Emissions
Complies with EN61326-1:2005 / EN61326-1:2006 Industrial Environment, Class A for radiated emissions
Required Airflow
> 2 m/s in situ for units dissipating > 30 W
In order to guarantee the above performance and specifications, PCI digitizer cards must be installed in a PCI metal
frame with adequate cooling. The card’s front panel must be screwed to lock the digitizer into place and insure
proper grounding of the frame. The frame must not be used without closing all vacant front panel slots to guarantee
EMC shielding and cooling. Similarly cPCI modules must be screwed to lock them into place and insure proper
grounding. The crate must not be used without closing all vacant front panel slots to guarantee EMC shielding and
cooling.
