Keithley Instruments Inc. 7708 40 CHANNEL DIFFERENTIAL MULTIPLEXER MODULE
The Keithley 7708 is a 40-channel differential multiplexer module designed for use with Keithley Series 2700, 2701, and 2750 Multimeters/Data Acquisition/Switch Systems. It provides 40 channels of differential or 80 channels of single-ended multiplexer switching, plus two additional protected channels for current measurements. The module is ideal for automated test applications requiring high channel density and supports signal switching for voltages up to 300V and currents up to 1A. The 7708 features built-in cold junction compensation for thermocouple measurements and is compatible with a wide range of signal types, including voltage, resistance, frequency, and temperature. Its design ensures reliable, low-noise signal routing and easy integration into automated test setups.
