PXI & CompactPCI Compliance
The module is compliant with the PXI Specication 2.2. Local Bus,
Trigger Bus and Star Trigger are not implemented.
Uses a 33MHz 32-bit backplane interface.
Safety & CE Compliance
All modules are fully CE compliant and meet applicable EU
directives: Low-voltage safety EN61010-1:2010, EMC Immunity
EN61326-1:2013, Emissions EN55011:2009+A1:2010.
Mechanical Characteristics
Single slot 3U PXI (CompactPCI card).
3D models for all versions in a variety of popular le formats are
available on request.
Connectors
PXI bus via 32-bit P1/J1 backplane connector.
Signals via front panel 50-pin male D-Type connector, for pin outs
please refer to the operating manual.
Note: Care must be taken when interfacing the module with
external circuits which may produce high voltage spikes or RF
interference. Additional noise protection may be required, please
contact Pickering if you wish to discuss your requirement.

† Outputs may be paralleled to increase current capability.
Power Outputs
Choice of switched output voltages: +12V, +5V, +3.3V, -12V and
-5V supplied from DC-DC converter (40-228-001).
Up to 4A for +3.3V and +5V, 1A for -5V and ±12V.
Output signals are controlled using an externally supplied 3.3V,
50mA, control line (40-228-001) or onboard output (40-228-002).
