Description
The NI-9421 is a robust C Series Digital I/O module characterized by its unique part numbers, including 779002-01, 779136-01, 779136-02, and 783734-01. This module stands out for its 8 digital input channels which employ sinking inputs technique, making it highly versatile for various industrial applications.
One of the key features of the NI-9421 is its compatibility with 12V and 24V digital I/O logic levels, ensuring broad applicability across different electrical standards. The module provides excellent isolation levels, with 250 Vrms Channel-to-Earth Ground isolation for part numbers 779002-01 and 783734-01, and 60 VDC Channel-to-Earth Ground isolation for part numbers 779136-01 and 779136-02, enhancing its safety and reliability in demanding environments.
Additionally, the 779136-02 part number is uniquely conformal coated, offering extra protection against harsh conditions, making it an ideal choice for challenging industrial applications. When it comes to energy consumption, the NI-9421 is designed to be efficient, with a power consumption of up to 240 mW in its active state and just 7 mW in sleep mode.
Despite its powerful features, the module is lightweight, weighing in at only 5.1 oz, and it operates reliably in a wide temperature range from -40 °C to 70 °C and can be stored in temperatures ranging from -40 °C to 85 °C. Its operational and storage humidity ranges are 10% RH to 90% RH and 5% RH to 95% RH, respectively, both non-condensing, ensuring its performance remains stable under fluctuating environmental conditions.
