The National Instruments part number 778572-67 refers to the PXI-2567 Relay Module, a high-performance device designed for versatile relay applications within PXI systems. This module features 64 independent relay channels, each capable of driving a maximum current of 600 mA and a maximum voltage of 50 V DC. It operates with an internal power supply requirement of 5 V at 1.25 A or 12 V at 0.5 A. The single-channel operation time is rated at a rapid 60 μs, enhancing system responsiveness. Eight addressable trigger lines provide programmable control through compatible software, requiring a pulse width of at least 150 ns for effective operation. The output supports programmable trigger control signals ranging from 1 μs to 62 μs on trigger lines indexed from 0 to 7. The module is equipped with a 78-pin D-SUB I/O connector, facilitating easy integration into control systems.

With a total power consumption of 8 watts at 5 volts or 0.5 watts at 3.3 volts, this module's compact dimensions are 21.6 × 2.0 × 13.0 cm (8.5 × 0.8 × 5.1 in.) and it weighs approximately 220 grams. It operates effectively within a temperature range of 0 °C to 55 °C and can be stored between -20 °C and 70 °C. The module is designed for environmental resilience with an operating humidity range of 5% to 85% (non-condensing) and meets a pollution degree level of 2. It can be mounted up to 2000 meters above sea level and is built to withstand operational shock of 30 g peak, half-sine, 11 ms pulse (per IEC 60068-2-27), and operational vibrations ranging from 5 Hz to 500 Hz at 0.3 grms, while non-operational vibrations reach up to 2.4 grms (per IEC 60068-2-64). The PXI-2567 Relay Module does not include internal protection class certification, thus it should be maintained in a dry and clean environment to safeguard its components and ensure optimal performance.
