The 40-618A Source Switching Module consists of 12 separate
4-channel multiplexers and 44 uncommitted SPST relay contacts in a
single width PXI module. Typical applications include signal routing for
avionics test systems that conform to the ARINC 608A specification.
Switching is performed using high quality electro-mechanical signal
relays with 2A switch/carry current and
voltage handling of 300VDC/250VAC.
The signal breakdown voltage is
greater than 500V.
The multiplexers of the 40-618A can
be operated in the conventional way
with break-before-make action when a
new channel is selected. Alternatively,
product variants can be supplied
that allow multiple channels to be
simultaneously selected.
The 40-618A channel selection
configurations have been revised from
the 40-618. The 40-618A defaults to
single channel selection with multiple
channel selection variants defined by
use of a suffix.
Other configurations for this module can
be supplied, please contact Pickering
Interfaces with your requirements.
Pickering PXI Modules
are compatible with Mass
Interconnect solutions
from both VPC and MAC
Panel. Shown is the
40-618A module with the
terminal block for the
