Product Overview

The 7708 from Keithley is a 40-channel differential multiplexer module with automatic CJC screw terminals. This 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 model 7708 ideal for RTD, thermistor and thermocouple temperature applications. It is also well suited for mixed signal measurement applications that require multi-point monitoring, such as environmental stress screening. It has >10^10 ohm (<100pF) isolation between any two terminals, >10^9ohm (<200pF) isolation between any terminal and earth, <-40dB cross talk (10MHz, 50W load) and : <0.1dB below 1MHz/<3dB below 2MHz insertion loss (50W source, 50W load). The common mode voltage is 300V between any terminal and chassis. The maximum signal level is channels (1-40): 300VDC or RMS, 1A switched, 60W, 125VA maximum.
  • 40 channels for general purpose measurements
  • Two- or four-wire measurement
  • Oversize screw terminal connection blocks are standard for easier connection
  • 300V, 1A capacity for voltage channels (60W, 125VA)
  • Relay closures stored in onboard memory
  • Latching electromechanical relays, actuation time is less than 3ms
  • Offset current is less than 100pA, connector type is screw terminal, #20AWG wire size
  • Operating temperature range from 0°C to 50°C and weight is 0.52Kg
