Description
The Part Number 189419D-01 refers to a component within the C Series Digital I/O category, specifically the NI-9481 model. This model features 4, SPST Relays channels which are capable of handling a maximum voltage of 30 VDC (2 A), 60 VDC (1 A), 250 VAC (2 A). It is designed to be compatible with NI CompactDAQ or CompactRIO Chassis, ensuring a wide range of application uses.
The NI-9481 is equipped with interchangeable, CHa and CHb terminal types, providing flexibility for different wiring requirements. Additionally, it includes LED indicators to easily monitor the channel status, enhancing usability and troubleshooting efforts. For energy-saving purposes, the module features a sleep mode where the LEDs are deactivated.
To ensure optimal performance in environments prone to vibration, it is recommended to use 2-wire ferrules or the NI-9932 backshell kit. This recommendation underscores the importance of securing connections and maintaining integrity under such conditions.
