Keithley 7700 20 Channel Multiplexer Card

The Keithley 7700 is a 20-Channel, Differential Multiplexer Plug-in Module that offers 20 channels of 2-pole or 10 channels of 4-pole multiplexer switching that can be configured as two independent banks of multiplexers.

There are two additional protected channels for current measurements. Automatic CJC is provided so that no other accessories are required to make thermocouple temperature measurements. In addition, the 7700 contains latching electromechanical relays that enable signal bandwidths of up to 50MHz. The 7700 is ideal for RTD, thermistor, and thermocouple temperature applications.
