Multiplexer/Matrix

Configure Page for: Print PDF Rich Text
  • Software configurable
  • 64, 32, or 16-channel multiplexer modes (SCXI-1331)
  • Up to 786x1 (1-wire) multiplexer in a single SCXI chassis
  • Expand your channels without complicated wiring

The National Instruments SCXI-1127 (electromechanical relay) and SCXI-1128 (solid-state relay) are devices that function as multiplexer or matrix modules. As a multiplexer, they can operate in different multiplexing modes, such as 1-wire for resistive measurements including RTDs and low-resistance measurements. With the SCXI-1332 front-mounting terminal block, the SCXI-1127 and SCXI-1128 become an 4x8 2-wire matrix. Expanding the multiplexer or matrix channel count is as easy as adding additional modules.
