Overview of 40-630A/632A Multiplexer Configurations
(see overleaf for detailed diagrams)
The 40-630A/632A general purpose multiplexer modules feature a
wide range of switching congurations. They are based on 1-pole
or 2-pole reed relays and typical applications include signal routing
in ATE and data acquisition systems. User connections are made
via a front panel 68-pin socket.
The 40-630A/632A can be operated as conventional multiplexers
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 630A/632A channel selection congurations have been revised
from the 40-630/632. The 40-630A/632A defaults to single channel
selection with the multiple channel selection variant dened by use
of a sufx.
Automatic isolation switching (see diagrams overleaf) connects
only the currently active multiplexer bank to the common terminal.
This minimizes capacitive loading and leakage current in large
multiplexer systems. Larger multiplexers may be constructed by
daisy chaining the common signals from multiple modules.
Automatic isolation switching only applies to single channel
selection mode, for versions with multi channel selection, the
isolation relays are controlled separately from the channel relays.
To prolong contact life of the isolation relays it is strongly advised
that they are cold switched.
