National Instruments PXI-2568 Relay Module

The National Instruments PXI 2568 (Part Number: 778572-68) is a broadly useful 31-channel Relay Module, highlighting free SPST (Form A) armature relays. Each relay is latching with low on-resistance and low thermal offsets. The NI PXI 2568 can switch up to 2 A at 30 VAC/30 VDC. With an effective coupling of voltage/current capacity and relay density, the PXI 2568 is perfect for automated test equipment (ATE) loads or for controlling heaters, lights, and fans. This model can expand throughput in automated test applications by the utilization of scanning. Scanning enhances throughput by downloading a list of up to 32,000 connections with the switch and cycling through the list by utilizing an event (trigger) with no intrusion from the host processor. Scanning is most effectively achieved by mating the PXI-2568 with an instrument, such as the NI PXI-4070 61 ⁄2-digit FlexDMM, which issues a trigger after every estimation. The device is equipped with a 62-pin male DSUB I/O connector. It has a power requirement of 6 W at 5 V, and 2.5 W at 3.3 V.

 All National Instruments PXI switch modules come with NI-SWITCH, an IVI-agreeable driver offering complete usefulness for all switch modules. For extra help with arranging, programming, and overseeing higher-channel-count switching frameworks, NI Switch Executive programming offers a simple-to-utilize smart switch management and visual routing environment.

The NI PXI-2568 Relay Module offers 31 autonomous SPST relays, maximum switch capacity up to 150 VDC, 150 VAC, latching relays, 32,000-step scanlist for deterministic examining, fully programmable software, a scan rate of 145 cycles/s, a switch bandwidth of 40 MHz, tight synchronization with instruments through hardware triggers, operating systems, Windows 2000/NT/XP Recommended Software, LabVIEW™, and LabWindows™/CVI™.

The PXI-2568 weighs 8 oz, and measures 8.5 x 0.8 x 5.1 in. in physical dimensions. It has recommended operating and storage temperature ranges of 0 to 55 °C and -20 to 70 °C respectively, non-condensing operating and storage temperature ranges of 10% to 90% RH and 5% to 95% RH respectively, operating and non-operating random vibrations of 0.31 grms and 2.46 grms respectively–at a frequency range of 5 to 500 Hz.
