The National Instruments 785673-01 (RMC-8357) is a 1U rackmount external controller engineered for high reliability in test and measurement applications, specifically designed for PXI Express systems. It is powered by an Intel Xeon E5-2620 v4 eight-core processor, offering exceptional performance tailored for demanding computational tasks. Supporting up to 32 GB of DDR4 SDRAM, this controller excels in environments that require significant processing capability and high data throughput.

The 785673-01 features a versatile storage management system capable of accommodating four front-accessible removable 2.5-inch drives, allowing users to expand storage capacity or configure RAID setups for enhanced data redundancy and performance. The drive interface utilizes SATA III technology to ensure high-speed data transfer, making it compatible with both solid-state and traditional hard disk drives for improved access times and reliability.

Designed for operational flexibility and reliability, the controller accepts both AC and DC power inputs, with a voltage range of 100 to 240 VAC and 23 to 36 VDC. This adaptability ensures compatibility across diverse installation environments. To further enhance operational reliability, it supports redundant power supply options, safeguarding against unexpected power supply failures.

Connectivity is robust, featuring four USB 3.0 ports, two USB 2.0 ports, and two RJ45 LAN ports for networking purposes. Video outputs are available via DVI and DisplayPort, alongside an optional PCIe graphics card for enhanced visual capabilities. Additionally, two RS-232 serial ports facilitate interfacing with various external devices.

The 785673-01 has been rigorously tested to meet industrial standards for mechanical shock and vibration, withstanding shocks of up to 30 g and operational vibrations within a frequency range of 5 to 500 Hz. Its wide operating temperature range of 0°C to 50°C and high humidity tolerance further solidify its suitability for demanding industrial applications.
