Model 3722 dual 1x48 high density multiplexer card
The Model 3722 has two independent banks of 1x48 two-pole multiplexers, which is ideal for
applications that require a high channel count. The two banks can automatically be connected to
the Series 3700 mainframe backplane and optional DMM through the analog backplane
connection relays. This connection allows the mainframe to reconfigure the card as a single
1×96 two-pole multiplexer, or to enable card-to-card expansion for even larger configurations.
Another feature of this card is the latching electromechanical relays that can accommodate
300V, 1A switched signal levels.
The Model 3722 uses two 104-pin D-sub connectors for signal connections. A solder-style
connector kit (Model 3792-KIT104-R) and pre-assembled cables (Models 3722-MTC-1.5 and
3722-MTC-3) are available for card connections.
