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 (COM) terminal and can handle up to 100 VDC/100 VAC or up to 1 A of current. With 40 channels per module, you can switch several hundred ATE loads in a single PXI chassis or thousands of channels in a multiple-chassis configuration. All National Instruments PXI switch modules are shipped with NI-SWITCH, an IVI-compliant driver of fering com p l ete functionality for all sw itch modules. For additional assistance in con f i g u ri n g, progra m m i n g, and managing high er- ch a n n el - count switching systems, NI Switch Executive software offers an easy-touse, intelligent switch management and visual routing environment. Ordering Information Automatic Scanning NI PXI-2570 ..................................................................778572-70 The PXI-2570 is able to maximize throughput in automated test applications by the use of scanning. Scanning improves throughput by downloading a list of up to 32,000 connections to the switch and c ycling thro u gh the list using an event (tri gger) without any interruption from the host processor. Scanning is most efficiently accomplished by mating the PXI-2570 with an instrument, such as the NI PXI-4070 61⁄2-digit FlexDMM, which issues a trigger after each measurement. Includes switch module, NI-SWITCH driver software.
