34931A Dual 4x8 Armature Matrix
The 34931A dual 4x8 armature matrix contains two matrices, each with 32 2-wire
crosspoint latching armature relays organized in a 4- row by 8- 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 intersects to create the crosspoint. For example, channel
304 represent the crosspoint connection between row 3 and column 4 (all
columns consisting of two digits; in this case the digits are 04). See the simplified
schematic below.
