5 Matrix Switch Modules
34932T Terminal Block
This terminal block with screw- type connections is labeled with the
model number and the abbreviated module name. In addition, space is
available on the label for you to write the slot number.
The 34980A Product Reference CD (shipped with the instrument)
contains a 34932T Wiring Log for you to document your wiring
configuration for this module. You can open the wiring log file in
Microsoft® Excel® or Adobe® Acrobat® format
NOTE
All modules that connect to the internal DMM are interlock
protected. This means that when an installed module is exposed (no
terminal block or cable is connected), the Analog Bus relays, which
are on Matrix 2, are open and disconnected from the Analog Buses.
See page 162 for further information.
Although they have
separate screw-type
connectors, rows
labeled the same on a
matrix are electrically
connected. Therefore,
you can wire the
same-matrix rows in
two locations.
Although columns are numbered the same on Matrix 1
and Matrix 2, they are electrically separate from one
another (e.g., Col C13).
