This document lists specifications for the NI PXI-2570 (PXI-2570) general-purpose relay module. All specifications are subject to change without notice. Visit ni.com/manuals for the most current specifications. Specifications characterize the warranted performance of the instrument under the stated operating conditions.

2023年2月18日 · Typical specifications describe the performance met by a majority of models. Nominal specifications describe an attribute that is based on design, conformance testing, or supplemental testing. Specifications are Typical unless otherwise noted. Specifications are valid at 23 °C unless otherwise noted.

The National Instruments PXI-2570 is a 40-channel, general-purpose switch module. Featuring independent SPDT (Form C) relays, the NI PXI-2570 maximizes relay density in a single PXI slot. Each relay contains a normally closed (NC), normally open (NO), and common terminal (COM) and can handle up to 100 VDC/100 VAC or up to 1 A of current.

The PXI‑2575 is a high‐density PXI multiplexer switch module that is ideal for high‑channel‑count automated test applications. It uses electromechanical relays and can route hundreds of signals to measurement devices or from source units.

Description: 40 independent SPDT relays/Latching relays/Fully software programmable. Manufacturer: National Instruments Corporation.
