Keithley 3732 Matrix Card, Quad 4X28 Reed Relay

Product Highlights

The ultra-high density Model 3732 matrix card is comprised of four banks, each with 4 rows by 28 columns of reed relays. This provides 448 single-pole crosspoints for maximum connection versatility in high channel count applications. For even greater flexibility, bank configuration relays are mounted on the card. They offer an automated method of connecting banks to enable two additional matrix configurations: single 4x112 and dual 4x56. This feature allows the matrix size to be easily adapted to existing or future applications. For differential (2-wire) measurements, a two-pole mode can be selected that enables automatic pairing of crosspoints to create a dual 4x28 or single 4x56 configuration. For larger matrix sizes, analog backplane relays are provided that enable rows to connect to the Series 3700 mainframe backplane. This allows, for example, a matrix of up to 4 rows by 672 columns within a single 3706 mainframe using six Model 3732 cards.
