The NI WSN-3212 measurement node is a wireless device that provides four 24-bit thermocouple input channels and four bidirectional digital channels that you can configure on a per-channel basis for input, sinking output, or sourcing output. The 18-position screw-terminal connector delivers direct connectivity to J, K, R, S, T, N, B, and E thermocouple types. You can power the measurement node with four 1.5 V, nonrechargeable AA alkaline cells, with operation up to three years on battery power, or externally power the node with a 9 to 30 V supply (not included).
A 2.4 GHz radio wirelessly transmits data to the WSN gateway, where you can connect through Ethernet to other network devices. NI-WSN software delivers easy network configuration in NI Measurement & Automation Explorer (MAX) and data extraction with NI LabVIEW software. The nonprogrammable WSN-3212 does not include a license to target and program the node with the LabVIEW Wireless Sensor Network (WSN) Module Pioneer.
You can configure the WSN-3212 as a mesh router to increase network distance and connect more nodes to your WSN gateway. You can connect eight end nodes (star topology) or up to 36 measurement nodes (mesh topology) to a single WSN gateway, with outdoor range up to 300 m with line of sight. The device also offers industrial temperature and shock and vibration ratings.
