The Keithley 7703 plug-in module offers 32 channels of 2-pole or 16 channels of 4-pole multiplexer switching that can be configured as two independent banks of multiplexers. The non-latching reed relays provide high speeds and are designed for 300 volt, 500 mA; 10 VA. The relay closures are stored in onboard memory. Typical applications for the 7703 is for RTD and thermistor temperature. * 32 channels for general purpose measurements * Relay actuation time of less than 1ms for high-speed scanning * Two- or four-wire measurement * Two 50-pin female D-sub connectors are standard for secure hook-up and quick teardow https://elecena.pl/product/27220283/keithley-7703-32-channel-hi-speed-differential-multiplexer 2024-11-11 https://elecena.pl/product/27220283/keithley-7703-32-channel-hi-speed-differential-multiplexer 2025-04-05 https://elecena.pl/product/27220283/keithley-7703-32-channel-hi-speed-differential-multiplexer 2025-05-05 https://elecena.pl/product/27220283/keithley-7703-32-channel-hi-speed-differential-multiplexer 2025-05-22 https://elecena.pl/product/27220283/keithley-7703-32-channel-hi-speed-differential-multiplexer 2025-06-09 https://elecena.pl/product/27220283/keithley-7703-32-channel-hi-speed-differential-multiplexer 2026-02-21 https://elecena.pl/product/27220283/keithley-7703-32-channel-hi-speed-differential-multiplexer 2026-07-09
