Wireless DAQ modules and enclosures

National Instruments has announced six wireless and ethernet data acquisition modules and two ingress protection (IP) enclosures for remote monitoring and control in harsh environments.

The modules combine high-voltage digital I/O and IEEE 802.11b/g (Wi-Fi) or ethernet communication to remotely monitor and control actuators such as pumps, valves and relays. Engineers and scientists can use these and other NI Wi-Fi or ethernet devices with the NI 9921 and NI 9922 IP enclosures to protect their equipment from dust particles and splashing water or rain in outdoor or industrial environments.

The NI WLS-9421 and WLS-9472 Wi-Fi DAQ devices provide eight channels of digital input and output, respectively, with 24 V logic levels. NI ENET-9421 and ENET-9472 ethernet DAQ devices offer these same measurements over a standard ethernet connection. The NI WLS-9481 and ENET-9481 provide four electromechanical relay outputs capable of switching up to 2 A at 30 VDC or 1 A at 60 VDC.

The NI 9921 and NI 9922 are environmentally sealed IP enclosures that simplify the installation of NI Wi-Fi DAQ devices in harsh outdoor or industrial applications by protecting them from dust and splashing water or rain. The NI 9921 enclosure provides a minimum of IP 54-rated connectivity for passing I/O signals and an external antenna for communication to a host PC. The NI 9922 enclosure offers an additional ethernet port and a four-pin trigger connector, which are also protected from environmental conditions.
