Switch Control
A matrix switch connects multiple inputs to multiple outputs. A matrix is arranged
in rows and columns. For example, the U2751A is a 4×8 matrix that can be used to
connect four sources to eight test points as shown in
Any column can be connected to any row by activating the corresponding relay
that connects the column to the row as shown in
relay on this module has its own unique channel label representing the row and
column. For example, channel 302 represents the cross-point connection between
row 3 and column 2.
Be aware that it is possible to connect more than one source to the same point
with a matrix. It is vital to make sure that these connections do not create
dangerous or unwanted conditions.

Note: Three-digit channel numbers are derived from
the intersection of the rows and columns, with the
last two digits representing the columns. The
intersection shown represents channel 202
