The 50-670C series of very high density multiplexer
cards feature a wide range of switching configurations.
Typical applications include signal routing in ATE and
data acquisition systems.The 50-670C shares the same
architecture as the established PXI 40-670A.
The card is factory set into one of the multiplexer
configurations shown in the table below. Connections are
made via a front panel 200-pin socket.
50-670C Very High Density Multiplexer Range
• 1-Bank, 198 Channels, 1-Pole
• 1-Bank, 99 Channels, 1-Pole or 2-Pole
• 1-Bank, 49 Channels, 2-Pole or 4-Pole
• 1-Bank, 24 Channels, 4-Pole or 8-Pole
• 1-Bank, 10 Channels, 8-Pole or 16-Pole
• 1-Bank, 5 Channels, 16-Pole
The 50-670C 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 50-670C-022-198/1 multiplexer.

eBIRST test tools simplify switching fault-finding by quickly
testing the system and graphically identifying the faulty relay.

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that has been superseded by a Pickering commissioned form, fit,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.
Model 50-670C channel selection configurations have been revised
from model 50-670A. The 50-670C family defaults to single channel
selection with multiple channel selection variants defined by use of
a suffix.
Built in automatic isolation switching (available in 1, 2 and 4-pole
configurations) connects only the currently active multiplexer
bank on to the analogue common, keeping capacitive loading and
leakage current in large multiplexer systems to a minimum. Larger
multiplexers may be constructed by daisy chaining the common
signals from multiple cards.
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.
