Description
The NI-9421 is a C Series Digital I/O module that features 8-CH 24VDC Sinking Digital Input capabilities. It operates efficiently with 8 digital input channels that are capable of handling logic levels of 12V and 24V for digital I/O operations. This module is particularly noted for its part numbers 779002-01, 779136-01, 779136-02, and 783734-01, each designed to cater to specific operational needs and configurations.
One of the critical aspects of the NI-9421 is its Channel-Earth Ground Isolation, which varies depending on the part number. For part numbers 779002-01 and 783734-01, the isolation is rated at 250 Vrms, while for 779136-01 and 779136-02, it stands at 60 VDC. Additionally, the model designated as 779136-02 is uniquely conformal coated, providing extra protection against environmental factors.
Regarding power consumption, the module is designed to be energy-efficient with an active power consumption of up to 240 mW and a significantly reduced consumption of up to 7 mW in sleep mode. This efficiency does not compromise its performance in various environmental conditions. The NI-9421 operates effectively within a temperature range of -40 °C to 70 °C and has a storage temperature range of -40 °C to 85 °C. Moreover, it can withstand humidity levels from 10% RH to 90% RH during operation and 5% RH to 95% RH during storage.
The robustness of the NI-9421 is further underscored by its resilience to vibrations during operation, withstanding Random vibrations of 5 grms and sinusoidal vibrations, ensuring reliable performance under various industrial conditions. This module exemplifies the integration of performance, durability, and efficiency suitable for a wide range of digital input applications.
