National Instruments 778572-86 PXI relay module.

The part number 778572-86 from National Instruments is the identifying part number for the PXI-2586 PXI relay module. This module features 10-channel Single-Pole Single-Throw (SPST) and 5-channel double-pole single-throw topology designed for applications requiring high channel counts and reliability. Each relay can handle a maximum switching voltage of 300 Volts channel to channel and 300 V, CAT II channel to ground with a maximum switching power for AC systems 3 kVA (up to 60 Hz) per channel, making it suitable for a wide range of signal-switching applications.

This relay module is designed to operate at an ambient temperature of 0 to 55 degrees Celsius and a storage temperature of -40 to 71 degrees Celsius with a relative humidity of 5% to 95%, noncondensing. This model requires to be used in indoors only installed at an maximum altitude of 2000 meters and pollution degree of 2. This module is built to endure harsh conditions with an operating vibrations of 5 Hz to 500 Hz, 0.31 grms and operational Shock of 30 g peak, half-sine, 11 ms pulse (Tested in accordance with IEC 60068-2-27) standard.

The 778572-86 PXI Relay Module has a relay operating time of 15.4 ms, maximum allowing for fast switching operations. The relays have an expected mechanical life of 1 × 10^7 cycles and an electrical life ranging from 1 × 10^5 cycles at maximum load to 3 x 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. Output triggers are programmable with pulse widths ranging from 1 µs to 62 µs, providing flexibility in timing and synchronization with other instruments.

This PXI Relay Module is designed to fit into a two slot 3U PXI Express chassis. It has a 200-pin LFH connector for secure and reliable connections. 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 g. This module features electromechanical single-side stable relays with Silver-nickel contact material helping increase the life of the material and provide low contact resistance to ensure reliable connections.
