The Keithley 7708 40-Channel Differential Multiplexer Module w/Automatic CJC & Screw Terminals 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. It is also well suited for mixedsignal measurement applications that require multi-point monitoring, such as environmental stress screening.
