NI SCXI-1128

High-Voltage FET Multiplexer/Matrix Switch

  • 512-step scanlist for deterministic scanning
  • 8x4 2-wire matrix configuration with SCXI-1332 terminal block
  • Easy instrument synchronization with hardware triggers
  • Effortless matrix expansion
  • Fully software programmable
  • Configuration determined by terminal block

The National Instruments SCXI-1128 is a high-density FET switch module that can act as a multiplexer or matrix. As a multiplexer, the NI SCXI-1128 can operate in different multiplexing modes including 1-wire for large-channel-count systems, 2-wire for differential pair systems, or 3 and 4-wire modes for resistive measurements including RTDs and thermistor. With SCXI front-mounting terminal blocks, the SCXI-1128 becomes an 64x1 1-wire matrix, 32x1 2-wire matrix, 4x8 2-wire matrix, or 16x1 4-wire matrix.
