The National Instruments 778572-86, also known as the PXI-2586 PXI relay module, is a high-performance relay solution designed for demanding signal-switching applications. This module features a topology comprising 10 Single-Pole Single-Throw (SPST) channels and 5 Double-Pole Single-Throw (DPST) channels, enabling reliable operations in high-channel-count environments. Each relay supports a maximum switching voltage of 300 Volts from channel to channel and up to 300 Volts, CAT II channel to ground, with a maximum AC switching power of 3 kVA (up to 60 Hz) per channel. The module can operate effectively in temperatures ranging from 0 to 55 degrees Celsius and is suitable for storage between -40 and 71 degrees Celsius, with a relative humidity range of 5% to 95% non-condensing. Designed for indoor use, it operates at altitudes up to 2,000 meters under pollution degree 2 conditions. Constructed to withstand challenging environments, the PXI-2586 meets IEC 60068-2-27 standards for vibration and shock, with operational vibrations from 5 Hz to 500 Hz at 0.31 grms and a shock rating of 30 g peak, half-sine, 11 ms pulse. The module boasts an efficient relay operating time of 15.4 ms, allowing for rapid switching operations. It has an impressive mechanical life expectancy of 1 × 10^7 cycles and electrical longevity ranging from 1 × 10^5 cycles at maximum load to 3 × 10^4 cycles, ensuring long-term reliability. The module supports input triggers from PXI trigger lines <0...7> with a minimum pulse width of 150 ns and offers programmable output trigger pulse widths between 1 µs and 62 µs, enhancing synchronization with other instruments. Physically, the PXI Relay Module is designed to fit within a two-slot 3U PXI Express chassis and incorporates a 200-pin LFH connector for robust connectivity. The module dimensions are 21.6 cm × 2.0 cm × 13.0 cm (8.5 in. × 0.8 in. × 5.1 in.), and it weighs approximately 400 grams. This module employs electromechanical single-side stable relays with silver-nickel contact material, increasing durability while ensuring low contact resistance for dependable connections.
