National Instruments NI 9481 4-Channel Relay Module Used Tested Working
Used working. The NI-9481 directly connects to a wide array of industrial devices such as motors, actuators, and DC devices. Each channel provides access to an electromechanical relay for switching signals up to 60 VDC (1 A) or 250 Vrms (2 A), features channel-to-channel isolation, and has a LED that indicates the status. The shock and vibration rating for the NI-9481 is limited compared with other CompactDAQ and CompactRIO modules because of the mechanical relays on the module.
