The National Instruments SCXI-1127 is a 32-channel (2-wire) high-density armature relay module that can act as a multiplexer or matrix switch. As a multiplexer, the NI SCXI-1127 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 thermistors. With SCXI front-mounting terminal blocks, the SCXI-1127 becomes an 64x1 1-wire multiplexer, 32x1 2-wire multiplexer, 16x1 4-wire multiplexer, or 4x8 2-wire matrix. Expand the measurement power of your digital multimeter (DMM), or build a complete ATE switching system for all of your instruments, with one or more of these modules.
