40-670C-022 198-Channel 1-Pole Multiplexer
The 40-670C module features a wide range of multiplexer
configurations based on high performance ruthenium reed
relays. Typical applications include signal routing in ATE
and data acquisition systems. User connections are via a
front panel 200-pin socket.
40-670C Very High Density Multiplexer Range:
198-Channel, 1-Pole (with isolation switching)
99-Channel, 2-Pole (with isolation switching)
99-Channel, 1-Pole (with isolation switching)
49-Channel, 4-Pole (with isolation switching)
49-Channel, 2-Pole (with isolation switching)
24-Channel, 8-Pole (with isolation switching)
24-Channel, 4-Pole (with isolation switching)
10-Channel, 16-Pole (no isolation switching)
10-Channel, 8-Pole (no isolation switching)
5-Channel, 32-Pole (no isolation switching)
5-Channel, 16-Pole (no isolation switching)
The 40-670C can be operated as a conventional multiplexer
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.
Note: The multiple channel selection option is not available
for the 40-670C-022-198/1 multiplexer.
Model 40-670C channel selection configurations have been
revised from model 40-670A. The 40-670C family defaults
to single channel selection with multiple channel selection
variants defined by use of a suffix.
Versions with automatic isolation switching (see range
table) connect only the active multiplexer bank to the
common terminal, thereby keeping capacitive loading
and leakage currents in large multiplexer systems to a
minimum. Larger multiplexers may be constructed by daisy
chaining the common signals from multiple modules. (Multiple channel selection not available for this version)
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.
Front Panel Connector
This product is based on the obsolete Molex LFH series
connector that has been superseded by a Pickering
commissioned form, fit, function equivalent. The new
connector series is 100% compatible with the Molex
connectors allowing either gender of Pickering connector
to mate with the corresponding Molex part without issue.
