National Instruments Corporation NI 9482, 30/60 VDC, 250 VAC, EM Form A, 4-Ch SPST Relay Module
The NI 9482 is a C Series relay output module designed by National Instruments for use with CompactDAQ and CompactRIO systems. It features four channels of electromechanical (EM) Form A (SPST) relays, supporting switching of up to 30 VDC at 1.5 A, 60 VDC at 1 A, or 250 VAC at 1.5 A per channel. The module is engineered for switching higher voltages and currents than solid-state modules, making it suitable for industrial control, signal switching, and actuator driving applications. The NI 9482 provides channel-to-channel isolation and is hot-swappable, ensuring flexibility and safety in system integration. It is compatible with a wide range of C Series chassis and is supported by NI-DAQmx driver software for configuration and programming.
