The Keithley 7708 is a Plug-In Module that offers 40 channels of 2-pole or 20 channels of 4-pole multiplexer switching. It can be configured as two independent banks of multiplexers. The built-in CJC sensors automatically linearise thermocouples, making the Model 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. * 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 * Manufacturer's part: Keithley 7708 https://elecena.pl/product/27220280/keithley-7708-40-channel-differential-multiplexer-module 2024-11-11 https://elecena.pl/product/27220280/keithley-7708-40-channel-differential-multiplexer-module 2025-04-05 https://elecena.pl/product/27220280/keithley-7708-40-channel-differential-multiplexer-module 2025-05-05 https://elecena.pl/product/27220280/keithley-7708-40-channel-differential-multiplexer-module 2025-05-22 https://elecena.pl/product/27220280/keithley-7708-40-channel-differential-multiplexer-module 2025-06-09 https://elecena.pl/product/27220280/keithley-7708-40-channel-differential-multiplexer-module 2026-02-21
