SCXI-1127

32-Channel, Electromechanical Relay Matrix/Multiplexer Switch Module for SCXI—The SCXI‑1127 is a high-voltage, armature relay module that can act as a multiplexer or matrix switch. As a multiplexer, the 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 resistance temperature detectors (RTDs) and thermistors. With SCXI front-mounting terminal blocks, the SCXI‑1127 becomes a 64x1 1‑wire multiplexer, 32x1 2‑wire multiplexer, 16x1 4‑wire multiplexer, or 4x8 2‑wire matrix.
