shows the relay groupings for the Agilent E8782A.
(The Agilent E8783A is identical but does not have the
instrumentation relays.) Individual relays can be replaced on
the Agilent E8782A and E8783A 32-pin matrix modules. All
relays are 5V, 1A reed relays. The Agilent part number for an
8-pack of relays is 0490-2063. The tables on the following pages
list the component number for each possible relay. The tables
for the Measurement and Instrument Matrices are listed in a
row/column format. For example, in
connects Measurement Matrix Row5 to Column3 (Abus3) is
K305. Relay component numbers are silk-screened on the back
of the PC board.
Note that E8782A with ID 66
have Row to Aux relays.
