The National Instruments SCXI-1192 Relay Module is a high-performance device designed for handling RF signals up to 18 GHz. This module features eight single-pole double-throw (SPDT) relays, each offering two channels, allowing for flexible routing of high-frequency signals in various applications. It has a maximum rated voltage of 30 V and a maximum current capacity of 2 A at this voltage level. The SCXI-1192 is equipped with 24 screw-on SMA jacks for convenient I/O connections and utilizes latching electromechanical relays with gold-plated contacts, ensuring reliable performance under demanding conditions. Notably, the latching nature of the relays means that they maintain their state during power interruptions, eliminating a defined power-up state.

For operational flexibility, users can choose to auto-detect the SCXI-1192 and other SCXI modules, or manually add them to their system, depending on the specific requirements of their setup. When using the auto-detect feature, it is essential that the chassis be connected to an NI instrument if it is not an SCXI-2000 remote chassis. Users should also exercise caution by not removing the module from a powered chassis to prevent damage. The SCXI-1192 is capable of routing signals from two RF sources to a single RF measurement instrument, such as an oscilloscope, spectrum analyzer, or power meter.

While National Instruments has announced that the SCXI-1192 has reached an obsolete status, it remains available for purchase and repair through Apex Waves. The module measures 1.2 x 6.7 x 7.6 inches and weighs 2 lb 7 oz, and comes with a warranty of 2 to 3 years. Comprehensive user manuals and maintenance documentation are also available for download.
