The National Instruments PXI-2571 is a high-density relay module designed for versatile switching applications within the PXI platform. With 66 channels, this module employs high-performance free SPDT (Form C) relays, each equipped with normally closed (NC), normally open (NO), and common (COM) terminals. The PXI-2571 supports signal levels of up to 100 VDC or 100 VAC and a maximum current rating of 1 A, enabling the capability to handle multiple ATE loads effectively within a single PXI chassis or in a multi-chassis setup. The onboard control logic facilitates direct access to relay operations, including the ability to download up to 1024 scanning instructions, ensuring rapid and efficient switching cycles without necessitating controller interaction. Users can configure the scan list for either a single execution or continuous looping. Additionally, the switch control circuitry (SCC) allows for command loading through the provided driver software. The module also features an integrated measurement device that ensures proper signal routing and synchronization with external measurement systems. With a compact design measuring 8.5 x 0.8 x 5.1 inches and weighing only 6.1 oz, the PXI-2571 is both lightweight and space efficient. This product is backed by a 2-3 year warranty, and users can access the user and maintenance manuals available for download to assist with setup and operation.
