The National Instruments PXI-2568 Relay Module (Part Number: 778572-68) is a versatile 31-channel relay switch designed for demanding automated test equipment (ATE) applications. This module features 31 independent latching single-pole, single-throw (SPST) relays, each capable of switching loads up to 2 A at 30 VAC or 30 VDC, with a maximum voltage of 150 VDC and 150 VAC. The relays are characterized by low on-resistance and minimal thermal offsets, ensuring high performance and reliability. The PXI-2568 supports a scanning capability with a maximum scan list of 32,000 connections, enhancing throughput by allowing seamless operation without intervention from the host processor. It is particularly effective when paired with instruments such as the NI PXI-4070 61/2-digit FlexDMM, benefiting from hardware triggers for precise timing.

The module features a switch bandwidth of 40 MHz and a scan rate of 145 cycles per second, facilitating rapid and accurate measurements. It is equipped with a 62-pin male DSUB I/O connector and operates with a power requirement of 6 W at 5 V and 2.5 W at 3.3 V. Supported software includes NI-SWITCH driver for comprehensive switch functionality, alongside NI Switch Executive for simplified management and visual routing of high-channel-count switching systems. The dimensions of the PXI-2568 are 8.5 x 0.8 x 5.1 inches, with a weight of 8 ounces. It is designed to operate within a temperature range of 0 to 55 °C and has a storage temperature range of -20 to 70 °C. Additionally, it meets humidity specifications for non-condensing environments and is resilient to random vibrations. A three-year warranty is included, and user manuals for operation and maintenance are readily available for download.
