The 40-571A is a power multiplexer designed to simplify
the connection of a common set of test equipment to one
of a number of different devices for testing. It is ideal for
applications where the equipment needs to conduct the same
test process on a series of similar devices one at a time. It
is available in a variety of configurations that allow testing
with differing number of devices to be tested and different
connection widths to suit differing test equipment pin counts.
All versions of the 40-571A are in BRIC8 fomat occupying
8 PXI 3U mechanical slots, one of which provides the PXI
interface and power.
MUX size can be ordered with different widths (pole counts)
and with different numbers of relay cards to support varying
number of devices to be tested. For example, the fully
populated 40-571A can be ordered in configurations that
support:
• 6 test devices with 48 connections
• 12 test devices with 24 connections
• 18 test devices with 16 connections
• 24 test devices with 12 connections
• 48 test devices with 6 connections
The pin layout of user connection is arranged to simplify the
cabling design. All versions use high quality power electro-
mechanical relays.
The 40-571A can be operated as a conventional multiplexer
with break-before-make action when a new channel is
selected. Alternatively, 6, 12, 16 and 24-pole variants of the
multiplexer can be supplied that allow multiple channels to be
simultaneously selected.
Note: The multiple channel selection option is not available for
48-pole versions of the multiplexer.
The 40-571A channel selection configurations have been
revised from the 40-571. The 40-571A module defaults to
single channel selection with multiple channel selection
variants defined by use of a suffix.
