Description
The Part Number for this device is 189419B-01, indicating its unique identification within its category. Speaking of which, it falls under the Category of C Series Digital I/O, specifically designed to cater to a wide range of digital input/output needs.
The Model of this device is the NI-9481. It serves as a cRIO-9481, 4-Channel General Purpose SPST Relay Module. This description highlights its purpose and functionality in providing general-purpose single-pole single-throw (SPST) relay operations across four channels.
When delving into the specifics of its capabilities, it is noted that it has 4, single-pole single throw (SPST) relays. This configuration allows for effective control and switching capabilities within your system. Its Compatibility with NI CompactDAQ or CompactRIO Chassis ensures that it can be seamlessly integrated into existing setups without compatibility issues.
The Maximum Voltage ratings are quite versatile, with the module capable of handling 30 VDC (2 A), 60 VDC (1 A), and 250 VAC (2 A). This range allows for a wide variety of applications and ensures that the module can handle significant power levels.
Each of the four channels has 2 interchangeable terminals (CHa and CHb), enhancing the module’s flexibility in connecting and configuring your setup. Additionally, there is a LED indicator for each channel, providing immediate visual feedback on the status of each relay, which is crucial for troubleshooting and monitoring.
Lastly, the Connection Recommendation advises the use of 2-wire ferrules for multiple wires per terminal; and recommends the NI-9932 backshell kit for conditions of extreme vibration. These recommendations are vital for ensuring a stable and secure connection, especially in environments where the module may be subjected to mechanical stress.
