National Instruments PXI-2571 PXI Relay Module
The NI PXI-2571 (Part Number: 778572-71) is a 66-channel, broadly useful switch module. Highlighting free SPDT (Form C) relays, the PXI-2571 expands relay density in a solitary PXI slot. Each relay contains a normally closed (NC), normally open (NO), and common terminal (COM), and can deal with up to 100 VDC/100 VAC or up to 1 A current. With 66 channels for each module, the user can switch a few hundred ATE loads in a single PXI frame or many channels in a multiple-chassis configuration. The onboard control logic for the NI PXI-2571 switch card gives the user guide access to open and close the relays and furthermore the capacity to download up to 1024 random scanning guidelines. The software included with the card naturally designs the NI PXI-2571 and downloads the output list hardware for the user. The scan list itself downloads straightforwardly into the memory of the card to deliver the quickest scan conceivable with no controller intercession. The user can configure the switch card to process the scan list once or to continuously loop through the scan list.
The switch control circuitry (SCC) oversees opening and shutting relays on the NI PXI-2571. The user can load commands for the SCC into memory storage by utilizing the driver programming they received with the unit. This model also includes an estimation device to start a scan, ensure scanning is empowered on the NI PXI-2571 before the estimation gadget begins to take estimations. This guarantees the switch card has the right signal routed and that the switch card is waiting for an outer trigger from the estimation gadget.
