The National Instruments SCXI-1127 is a 32-channel (2-wire) high density armature electromechanical relay module that can act as a multiplexer or matrix module. As a multiplexer, this module can operate in different 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. The SCXI-1127 is designed to work well with both low and high voltage signals.

The SCXI-1127 becomes a 64x1 1-wire matrix, 32x1 2-wire matrix, 4x8 2-wire matrix or 16x1 4-wire matrix through front-mounting terminal blocks. Using one ore more of these modules can expand the measurement power of your digital multimeter (DMM) or can build a complete ATE switching system for all of your instruments.
