National Instruments 784801-01

The National Instruments 784801-01 Interface Module, designated as the LV-222-555-555, is a high-performance avionics databus interface specifically engineered to support the MIL-STD-1553 protocol for both military and commercial applications. This module features two core I/O sites, each equipped with 64 MB of memory and 8 bidirectional TTL discrete I/O channels. User-controlled LED indicators on each core provide clear visual status feedback. The power requirements vary based on usage; with both cores active, the 784801-01 typically consumes 5.9 W at +3.3 V and 7.7 W at +12 V. Designed to facilitate advanced data handling, the module supports amplitude controls, playback with error injection, and hardware-controlled transmit scheduling, enabling sequential monitoring and precise time stamping for efficient data analysis. Built in a standard 3U PXIe form factor, measuring 100 x 160 mm and weighing 3.5 lbs (1.6 kg), the 784801-01 operates within a temperature range of -40 to 85 °C and can be stored safely from -55 to 100 °C. It is also designed to function in environments with non-condensing humidity levels from 0 to 95%. The module comes backed by a three-year warranty, ensuring reliability and performance for demanding applications.
