Description
The part number 198863D-01L identifies a specific C Series Digital I/O module, specifically the NI-9481 model. This module is a 4-Channel General Purpose SPST Relay Module, designed to handle a variety of tasks with its 4, Single-Pole Single Throw (SPST) Relays. It is compatible with NI CompactDAQ or CompactRIO Chassis, making it a versatile choice for integrating into existing systems.
The NI-9481 is capable of supporting a Maximum Switching Voltage of 30 VDC (2 A), 60 VDC (1 A), 250 VAC (2 A), which allows it to be used in a wide range of applications. Each of its four channels features two interchangeable terminals (CHa and CHb), providing flexibility in connection options. Additionally, each channel is equipped with its own LED, making it easy to monitor the status of each relay at a glance.
For environments where power conservation is important, the module includes a Sleep Mode that deactivates the LEDs to save energy. Furthermore, for applications that may involve vibration, it is recommended to use 2-wire ferrules or the NI-9932 backshell kit, ensuring a secure and reliable connection under such conditions.
