The National Instruments 782383-01, also known as the PXIe-2532B, is a high-density PXI matrix switch module tailored for high-channel-count automated testing applications. It leverages small reed relays capable of switching up to 2,000 cycles per second, making it ideal for fast testing scenarios. This module supports a wide range of matrix topologies, configurable through various terminal block accessories, ensuring flexibility to meet diverse testing needs. It handles up to 0.5 A of current per channel, whether in a switching or carrying capacity, and accommodates a maximum switching voltage of 100 V across channels and to ground. With a power handling capability of up to 10 W per channel, it is suitable for various applications. The 782383-01 boasts low initial DC path resistance of less than 1 Ω and a guaranteed end-of-life resistance of at least 2 Ω, providing excellent isolation with an open channel resistance exceeding 1 × 10^9 Ω. The precision of this module is enhanced by its thermal electromotive force (EMF) specifications, which are less than 50 µV for a 1-wire configuration and less than 20 µV for a 2-wire configuration. The onboard relay counting feature allows for deterministic operation and relay monitoring, while hardware trigger support facilitates increased testing throughput with a minimum pulse width of 150 ns for input triggers sourced from PXI trigger lines <0...7>. Constructed with reliable rhodium reed relays, the 782383-01 includes two 150-position Samtec ERM8-EM series I/O connectors. It operates effectively within a temperature range of 0 to 55 degrees Celsius and can be stored at temperatures between -20 and 70 degrees Celsius, conforming to Pollution Degree 2 standards for indoor use under relative humidity conditions of 5% to 85% non-condensing.
