The National Instruments SCXI-1128 is a 32-channel solid-state relay multiplexer/matrix switch module for the SCXI platform. NI documents its use in scanning systems and high-voltage signal routing through suitable SCXI backplanes.
Core content remains expanded and crawlable.
The SCXI-1128 provides solid-state relay switching in a multiplexer/matrix module. NI identifies it as a 32-channel SSR device in its supported-hardware documentation.
In a suitable SCXI switching system, the SCXI-1128 can use high-voltage backplanes to share signals among connected switches and route signals to a digital multimeter. NI's scanning guidance identifies its trigger-input and scanner-advanced signal paths; multimodule operation depends on the complete hardware setup.
