SCXI-1128

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.
