Keithley 7074
Multiplexer Card
Description
This multiplexer card consists of eight banks of 1 x 12 multiplexers that can be configured in various combinations.
Three pole switching (HI, LO, guard) is provided for any of the 96 inputs.
This unit is available with either dry or mercury wetted reed relays.
The dry reed version (Model 7074-D) has lower thermal offset performance, while the mercury-wetted version (Model 7074-M) offers minimal contact bounce for and constant contact resistance overlife.
