Description
The NI-9481 is a highly versatile 4-CHANNEL GENERAL PURPOSE SPST RELAY MODULE distinguished by its part number 198863C-01L. This module falls under the C Series Digital I/O category and is engineered to seamlessly integrate with NI CompactDAQ or CompactRIO Chassis, ensuring broad compatibility for various applications.
It features 4, Single-Pole Single Throw (SPST) Relays, designed to handle a variety of signals with a maximum voltage capacity of 30 VDC (2 A), 60 VDC (1 A), and 250 VAC (2 A). Each relay channel is equipped with two interchangeable terminals (CHa and CHb), allowing for flexible connection options.
To aid in the visual monitoring of the module’s status, an LED indicator is provided for each channel. This feature enables quick and easy identification of active channels, enhancing the usability of the module.
For wire termination, the use of 2-wire ferrules is recommended, especially when connecting multiple wires to a single terminal. This recommendation is in line with the module’s design to accommodate various wiring configurations while maintaining a secure and reliable connection.
Considering environments where the module may be subjected to vibration, it is advised to utilize ferrules for added connection stability. For enhanced protection against such conditions, the NI-9932 backshell kit is recommended, providing an extra layer of durability and ensuring the module’s longevity and consistent performance.
