TAMS USB Controlled 4 x 8 Matrix Switch (03-1848A)

The 4 x 8 matrix allows connection of any row (1 through 8) with any column (1 through 4). The matrix consists of 32 SPST relays (labeled 11 through 18, 21 through 28, 31 through 38, and 41 through 48) forming a 4 by 8 matrix switch, where any of the inputs 1 through 8 can be connected with any of the four “Analog Bus” lines. Five additional relays allow connect/disconnect of the matrix from the Analog Bus, as well as grounding selected terminals to the Analog Common to enable single ended measurements.  Large matrixes can be easily built by connecting the “Analog Bus” terminals together with short jumper cables.
