• 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. It is also well suited for mixed-signal measurement applications that require multi-point monitoring, such as environmental stress screening.
