The PXIe-2527 is a high‐voltage32‐channel, 2‐wire PXI multiplexer switch module. Use the PXIe-2527 for medium‐ to high‐density automated test applications that connect measurement or signal generation instruments to various test points on devices under test (DUTs) or units under test (UUTs).

Key Features

The PXIe-2527 has the following features and capabilities.

  • Sources up to 300 V and 2 A of drive capacity per channel
  • Provides high-power electromechanical relays (EMRs) and can be used as front end for the PXI DMM modules, offering channel expansion for a variety of measurements
  • Supports multiple channel configurations including 64x1 1‑wire, 32x1 2‑wire, and 16x1 4‑wire
  • Provides onboard relay counting for relay monitoring and deterministic operation with hardware triggers to improve test throughput
