Keysight Technologies 34923A Data Acquisition Terminal Block for 34980A Data Acquisition System

The Keysight 34923A module for the 34980A Multifunction Switch/Measure Unit is a high speed-multiplexer for general purpose scanning. It uses reed relays to achieve scan rates up to 500 channels-per-second. Use this module for high-throughput automated test applications as well as high-speed data logging and monitoring tasks.
Current measurements can be accomplished with user supplied shunts. Standard 50-pin Dsub connectors allow for use with standard cables, terminal blocks, or mass interconnect solutions. 2- and 4-wire channels may be mixed on the same module, or configure as an 80 1-wire multiplex

40 2-wire channels or 80 1-wire channels
Mixed 2- or 4-wire configurations
High-speed reed relays, with relay counter
500 ch/s scanning
