Keithley 3720 Dual 1×30 Multiplexer Card

Keithley Dual Multiplexer Plug-In Card, 37xx Series – Keithley 3720, The Keithley 3720 is a Dual 1×30 Multiplexer Plug-In Card that offers two independent banks of 1×30 two-pole multiplexers. It is ideal for general purpose switching, including temperature measurements. 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 to a single 1x 60 two-pole multiplexer or to enable card-to-card expansion for even larger configurations.Other features of the 3720 include its ability to be reconfigured to coordinated four-pole operation for additional measurement flexibility. Furthermore, the 3720 supports thermocouple type temperature measurements when used with the 3720-ST (screw terminal) accessory providing automatic cold junction compensation (CJC). The 3720 uses two 78-pin male D-sub connectors for signal connections. Keithley 3720 Dual 1×30 Multiplexer Card
