Each relay is latching with very low on-resistance and low thermal offsets. The NI PXI-2568 can switch up to 2 A at 30 VAC/30 VDC. With an efficient coupling of voltage/current capability and relay density, the PXI-2568 is ideal for automated test equipment (ATE) loads or for controlling heaters, lights, and fans. All National Instruments PXI switch modules are shipped with NI-SWITCH, an IVI-compliant driver offering complete functionality for all switch modules. For additional assistance in configuring, programming, and managing higher-channel-count switching systems, NI Switch Executive software offers an easy-to-use, intelligent switch management and visual routing environment. Automatic Scanning Ordering Information The PXI-2568 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 cycling through the list using an event (trigger) without any interruption from the host processor. Scanning is most efficiently accomplished by mating the PXI-2568 with an instrument, such as the NI PXI-4070 61⁄2-digit FlexDMM, which issues a trigger after each measurement.
