Description
The NI-9469 is a highly versatile Cabled Synchronization Module designed for use with C Series Specialty Modules. This product comes in two versions: the 781955-02 which is conformal coated for enhanced durability in harsh environments, and the 781955-01 which is the non-conformal coated variant. Manufactured by National Instruments, a leader in the field, this module is engineered to facilitate precise synchronization for digital input and output, as well as analog output modules. Additionally, it supports basic coding and signal routing tasks.
The NI-9469 features 12 input/output lines, consisting of 4 input and 8 output lines, and is equipped with 3 ports that employ differential signaling for improved signal integrity. It is compatible with three shielded RJ45 connectors, utilizing CAT 5e Ethernet cabling for connectivity. For ease of monitoring, the module is also outfitted with 4 green LED indicators that provide immediate visual feedback on the operational status.
One of the standout technical specifications of the NI-9469 is its Clock Generation (Direct Sequence Spread Spectrum, DSS) Frequency, which can reach up to 12.8 MHz or 13.1072 MHz. This capability is complemented by an impressive accuracy of ±3.5 ppm, ensuring precise synchronization across connected devices. The module supports a maximum cable length of 100 meters, with a maximum propagation delay of up to 4.98 ns/m, facilitating flexible setup configurations and reliable performance over long distances.
In terms of power efficiency, the NI-9469 boasts a maximum active power consumption of 1 W, and an extremely low power consumption of 25 µW in sleep mode. This makes it an energy-efficient choice for a wide range of synchronization tasks in various industrial applications.
