Model 3724 Dual 1x30 FET Multiplexer Specifications
The Model 3724 has two independent banks of 1×30 2-pole multiplexers. It is
ideal for general-purpose switching, including temperature measurements. 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 to a single 1×60
two-pole multiplexer, or to enable card-to-card expansion for even larger
configurations.
Other features of the Model 3724 include its ability to be reconfigured to
coordinated four-pole operation for additional measurement flexibility.
Furthermore, the Model 3724 supports thermocouple-type temperature
measurements with the Model 3724-ST (screw terminal) accessory, providing
automatic cold junction compensation (CJC).
The Model 3724 uses two 78-pin male D-sub connectors for signal connections.
For screw terminal or automatic CJC, use the detachable Model 3724-ST
accessory.
