The WSN-3202 is not recommended for new designs. NI recommends that you instead consider the WSN-3226, which offers four analog input channels like the WSN-3202 but adds support for resistance-based measurements such as RTDs. The WSN-3226 also features battery backup and industrial digital I/O levels.
The WSN-3202 measurement node is a wireless device that provides four ±10 V analog 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 sensors and offers a 12 V, 20 mA sensor power output that you can use to drive sensors that require external power. You can power the measurement node with four 1.5 V, AA alkaline cells, with operation up to three years on battery power, or externally power the node with a 9 V 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 Measurement & Automation Explorer (MAX) and data extraction with LabVIEW software. The nonprogrammable WSN-3202 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-3202 as a mesh router to increase network distance and connect more nodes to your 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 programmable input ranges to maximize measurement accuracy and industrial temperature and shock and vibration ratings.
Wireless products require certification based on the geographic region of use. Consult the Wireless Product Certifications document linked from the Resources tab to determine which products are certified in your region.
