The NI 9482 is a 4-channel, single-pole single throw (SPST) sourcing digital output module for NI CompactDAQ and CompactRIO. Each channel provides an SPST relay for switching signals up to 30 VDC (1.5 A), 60 VDC (1 A), 250 VAC (1.5 A) when all channels are being used. Each channel is electrically isolated from all other channels and from earth ground with 250 Vrms of continuous isolation. For quick reference, every channel features an LED to indicate the state of that channel. The NI 9482 allows for direct connection to a wide array of industrial devices such as motors, actuators, and DC devices.
