Analog Buses
NOTE: Three-digit channel numbers are derived from the
intersection of the rows and columns, columns having two
digits. The intersection shown here represents Channel
308 (Row 3, Column 8).
NOTE: Although columns are
numbered the same on Matrix 1
and Matrix 2, they are electrically
separate from one another.
NOTE: All series resistors shown
are 100
Ω.
NOTE:
Matrix Relays: Reed non-latching
Analog Bus Relays: Armature
