34932A Dual 4x16 Armature Matrix
The 34932A dual 4x16 armature matrix contains two matrices, each with
64 2- wire crosspoint latching armature relays organized in a 4- row by
16- column configuration. Every row and column are made up of two wires
each, a high (H) and a low (L). Each crosspoint relay has a unique
channel number representing the row and column that intersect to create
the crosspoint. For example, channel 315 represents the crosspoint
connection between row 3 and column 15 (all columns consisting of two
digits; in this case the digits are 15). See the simplified schematic below.
Matrix 1 and Matrix 2 are electrically separate from one another.
Matrix Relays: Armature latching. Analog Bus Relays: Armature non-latching
