- Keithley 3721, The Keithley 3721 Dual 1x 20 Multiplexer Plug-In Card that offers two independent banks of 1x 20 two-pole multiplexers that are ideal for general purpose switching, including temperature measurements. The two banks can automatically be connected to the Series 3700A mainframe backplane & optional DMM through the analogue backplane connection relays. This connection allows the mainframe to reconfigure the 3721 as a single 1x 40 two-pole multiplexer or to enable card-to-card expansion for even larger configurations. The 3721 provides a number of other features. In addition to the 40 channels, two fused channels are supplied for current measurements. The module
Includes:: dedicated inputs that enable 40 channels of four-wire common side ohms measurements. For thermocouple type measurements, automatic cold junction compensation (CJC) is supported when used with the 3721-ST (screw terminal) accessory. The 3721 uses two 50-pin male D-sub connectors for signal connections. Keithley 3721 Dual 1x 20 Multiplexer Card
