National Instruments 778572-76 PXI Multiplexer Switch Module
National Instruments part number 778572-76 is an identifying part number for the PXI-2576 a PXI Multiplexer Switch Module. It features 16 banks of 4x1 2-wire multiplexers. Its flexible architecture allows users to configure it in several topologies, making it suitable for parallel measurement tasks that require fewer channels. Users can also combine all the multiplexer banks to form a single multiplexer with 64 2-wire channels. Additionally, it offers relay counting for monitoring and deterministic operation with hardware triggers to improve test results. The NI 778572-76 relays are single-side stable.
When power is removed from the relay coil, the relay returns to its de-energized state, opening all the relays and disconnecting each channel signal from its corresponding common. The NI 778572-76 Multiplexer Switch Module tracks relay closures for each relay, increasing the count each time a relay is activated. Users can retrieve these counts automatically for predictive maintenance to reduce unexpected system downtime. NI measurement hardware is calibrated to ensure measurement accuracy and verify that the device meets its published specifications. To maintain ongoing accuracy, NI offers basic or detailed recalibration services, providing continuous ISO 9001 audit compliance and confidence in measurements.
This module is designed for Measurement Category I, suitable for signal voltages not exceeding 100 V. It can withstand impulse voltages up to 500 V. Avoid using this module for connections or measurements in Measurement Categories II, III, or IV. The relay type for this module is electromechanical and latching, providing reliable switching capabilities. Its relay contacts are made of silver and covered with gold, ensuring durability and efficient electrical conductivity. The module is equipped with an LFH matrix I/O connector with 50 positions, and an option for 160 positions, all male. Regarding power requirements, it consumes 2.5 watts at 3.3 volts and 10 watts at 5 volts, making it suitable for various applications where power efficiency and robust performance are essential.
