Keithley 3720 Multiplexer Card

Rent Keithley 3720 Dual 1x30 Multiplexer Card

The Keithley 3721 offers two independent banks of 1x20 two-pole multiplexers that are 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 Keithley 3721 as a single 1x40 two-pole multiplexer or to enable card-to-card expansion for even larger configurations. The Keithley 3721 provides a number of other features. Additionally to the 40 channels, two fused channels are supplied for current measurements. Also, the Keithley 3721 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 Keithley 3721-ST (screw terminal) accessory. The Keithley 3721 uses two 50-pin male D-sub connectors for signal connections. For screw terminal or automatic CJC, use the detachable Model 3721-ST accessory.

Features and Specifications of the Keithley 3720 includes:

  • 40 two-pole or 20 four-pole channels for general purpose switching
  • 2 dedicated channels for current measurements, 3A capacity
