Description
The product with the part number 189419E-01L falls under the category of C Series Digital I/O. Specifically, it is the NI-9481 model, which is a SPST Electromechanical Relay Module. This module boasts 4 channels, making it versatile for various applications.
It is designed to handle a maximum switching voltage of 30 VDC (2 A), 60 VDC (1 A), and 250 VAC (2 A), catering to a wide range of electrical requirements. Moreover, it is compatible with both NI CompactDAQ and CompactRIO chassis, ensuring easy integration into existing systems.
The module features CHa and CHb interchangeable terminals, providing flexibility in connection. Additionally, there is an LED indicator for each channel to display the current status, enhancing usability and monitoring capabilities. When in sleep mode, the LEDs are deactivated to conserve energy and reduce light pollution in dark environments.
For environments subjected to high vibration, it is recommended to use 2-wire ferrules or the NI-9932 backshell kit to ensure a secure and reliable connection. This recommendation underscores the module’s adaptability and durability in challenging conditions.
