Keithley 7708 40-channel Differential Multiplexer Module The Keithley 7708 40-channel Differential Multiplexer Module offers 40 channels of 2-pole or 20 channels of 4-pole multiplexer switching that can be configured as 2 independent banks of multiplexers. The built-in CJC sensors automatically linearise thermocouples, making the 7708 well-suited for RTD, thermistor and thermocouple temperature applications. It is also popular for mixed-signal measurement applications that require multi-point monitoring, such as environmental stress screening. The 7708 is for use with Keithley systems 2700 ( 760-0354 , 7600357 ), 2701 ( 760-0351 ) and 2750 ( 760-0360 ). 40 differential channels for general purpose measurements
2-wire or 4-wire measurements
300V 1A capacity for voltage channels, 60W 125VA
Oversize screw terminal connection blocks as standard, for ease of connection
Relay closures stored in onboard memory
