Specification
The 1260-37 switch module consists of two switch circuits; a 1 x
48 Signal Multiplexer/Scanner and a 40-Channel SPDT Switch.
The Signal Multiplexer circuit switches two lines per channel, and
has the capability of being configured as one 1 x 48 multiplexer,
two 1 x 24 multiplexers, four 1 x 12 multiplexers, or eight 1 x 6
multiplexers. The signal mulitplexer configuration is user
selectable, but is supplied from the factory in the one 1 x 48 two-
wire mode. In addition, the multiplexer may be configured as a
one-wire 1 x 96 multiplexer. A block diagram of this circuit is shown
in
Figure 3-1
. The 40 channel SPDT switch circuit provides 40
independent channels of switching. Each channel features one
common line that connects to either a normally open or normally
closed position. A block diagram of this circuit is shown in
