The National Instruments PXI-2565 is a robust 7 A, 16-channel Single-Pole Single-Throw (SPST) relay module specifically designed for high-current switching applications involving both AC and DC power sources. This PXI relay module excels in managing expectations for applications requiring up to 250 V AC and 125 V DC channel-to-channel maximum switching voltages, making it optimal for diverse general-purpose applications. The PXI-2565 is entirely software programmable and supports extensive instrument synchronization, ensuring seamless integration within your automation systems. Rated as measurement category II, this module is suitable for carrying voltages of up to 250 V AC and 125 V DC, while offering an impressive 1400 Vrms isolation between the backplane and input signals. Each channel can handle up to 5 A at 30 V DC maximum switching current, with a maximum switching power of 150 W and 1750 VA per channel. The device can also sustain a maximum carry current of 5 A DC and 7 A AC per channel, with a maximum switch load of 10 mA at 5 V DC. The non-latching electromechanical relays employed in this module feature gold-flash over silver alloy contacts, demonstrating reliable performance with a typical operation time of 5 ms and release time of 4 ms at 20 °C. The module's mechanical relay lifespan is rated at 50 million cycles, while its electrical lifespan extends to 100,000 cycles. Designed for efficient triggering, the PXI-2565 utilizes PXI trigger lines <0...7> with a minimum pulse width of 70 ns. Although this module will enter the NI Maintenance phase effective June 30, 2023, it will still be available for purchase through Apex Waves, ensuring continued access to this reliable hardware.
