Keithley 3722 Dual 1x48 High Density Multiplexer Card

The Keithley 3722 is a Dual 1x48 Multiplexer Plug-In Card that offers 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 3700A mainframe backplane and optional DMM through the analogue backplane connection relays.

This connection allows the mainframe to reconfigure the card as a single 1x96 two-pole multiplexer or to enable card-to-card expansion for even larger configurations. Another feature of this card is the latching electromechanical relays. They can accommodate 300V, 1A switched signal levels. The 3722 uses two 104-pin D-sub connectors for signal connections.
