Keithley Instruments 7708 Overview

  • 40 differential channels for general-purpose measurements
  • Two- or four-wire measurements
  • 300V, 1A capacity for voltage channels; 60W, 125VA
  • Oversize screw terminal connection blocks are standard for easier connection
  • Relay closures stored in onboard memory


  • The Keithley 7708 plug-in module offers 40 channels of 2-pole or 20 channels of 4-pole multiplexer switching that can be configured as two independent banks of multiplexers.
  • The built-in CJC sensors automatically linearize thermocouples, making the 7708 ideal for RTD, thermistor, and thermocouple temperature applications.
  • The 7708 is also well suited for mixed-signal measurement applications that require multipoint monitoring, such as environmental stress screening.
