Keithley 7708 Multiplexer Module 40-Channel Differential

Keithley 7708 Multiplexer Module (40-Channel Differential)

The Keithley 7708 is a high-density 40-channel differential multiplexer module engineered to deliver elite operational performance for multi-point monitoring in environmental stress screening and general-purpose measurements. By addressing the requirement for massive channel capacity, this 2-pole switching module can be configured as two independent banks, effectively minimizing measurement uncertainty through built-in CJC sensors that automatically linearize thermocouple signals. The metrological architecture of the 7708 ensures absolute traceability for RTD and thermistor applications, providing 2- or 4-wire measurement capabilities within a single professional-grade plug-in unit.

Built for industrial longevity, the 7708 features oversized screw terminal connection blocks as standard, facilitating rapid and secure field wiring for high-stakes testing. Its technical sophistication is highlighted by a 300V, 1A capacity and the ability to store relay closure counts in on-board memory for preventative maintenance audits. As a high-trust solution for managing complex measurement stimulus, the Keithley 7708 stands as an essential tool for technicians requiring high-resolution, multi-channel data acquisition in automotive, aerospace, and semiconductor testing environments.
