32-Channel, Solid-State Relay Matrix/Multiplexer Switch Module for SCXI—The SCXI-1128 is a high-voltage, solid-state switch module that can act as a multiplexer or matrix. As a multiplexer, the 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 resistance temperature detectors (RTDs) and thermistors. With SCXI front-mounting terminal blocks, the SCXI-1128 becomes a 64x1 1-wire matrix, 32x1 2-wire matrix, 4x8 2-wire matrix, or 16x1 4-wire matrix.
