Description
The 155304B-03L is a part of the C Series Digital I/O category, specifically the NI-9481 model. This product is a 4-Channel General Purpose SPST Relay Module that comes with a conformal coating for added protection. It is designed to handle 4 SPST Relay channels, making it versatile for various applications.
This module is compatible with NI CompactDAQ or CompactRIO Chassis, ensuring easy integration into existing systems. It boasts a maximum switching voltage capacity of 30 VDC (2 A), 60 VDC (1 A), and 250 VAC (2 A), catering to a wide range of electrical requirements.
Each channel on the module possesses two interchangeable terminals (CHa, CHb), providing flexibility in connection. Additionally, there is an LED indicator for each channel’s status, offering immediate visual feedback on the operation.
The NI-9481 is highly recommended for use with DC instruments, actuators, and motors, highlighting its suitability for a variety of industrial applications. For wiring, the use of 2-wire ferrules is recommended for connecting multiple wires in one terminal; for environments with extreme vibration, the NI-9932 backshell kit is advised, ensuring secure and reliable connections.
