Keithley Dual Multiplexer Plug In Card, 37xx Series Keithley 3720, The Keithley 3720 is a Dual 1x30 Multiplexer Plug In Card that offers two independent banks of 1x30 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 1x30 Multiplexer Card
