Pickering Interfaces
针对航天市场发布了两个最新的PXI开关模块。这种开关模块用于在航空电子测试系统中切换信号。这两款产品可以被用于任何3U的机箱中，也可以被用于Pickering的LXI机箱中。
Expanding its line of products for the aerospace market, Pickering
Interfaces has introduced two PXI switching modules that route
signals in avionics test systems. The modules can be used in any 3U
PXI chassis, as well as in Pickering’s LXI modular switching
chassis.
The 40-569 module comes as a fou-slot or eight-slot BRIC module
that integrates a 16-wire analog backplanes to accommodate resource
distributor and bus matrix input daughtercards in accordance with
Appendix D of the ARINC 608A specification. The scalable design
permits the inclusion of up to two resource distributor subsystems
and up to six bus matrix subsystems in an eight-slot BRIC module.
The 40-618 is a source switching module that implements the
switching functions defined in Appendix D of the ARINC
specification. It comprises 12 4:1 multiplexers and 44 SPST
uncommitted relays in a single-slot PXI module.
All modules employ electromechanical relays with 2-A switch/carry
current and 250-VAC/220-VDC voltage ratings.
Both the 40-569 and 40-618 are implemented in a 3U PXI format that
is compatible with the 60-100 LXI modular switching chassis,
permitting the modules to be controlled through either a PCI- or an
LXI-compliant interface.
