Web-based Data Logger DI-808
DATAQ DI-808 Web-based Voltage and Thermocouple Data Logger system. Features 8 isolated analog input channels programmable as a thermocouple or voltage input, 16-bit measurement resolution, and a full scale range of ±10mV to ±50V for voltage measurements or Thermocouple types J, K, T, B, R, S, E, or N.
Its built-in web server allows you to access, configure, manage, and oversee in real time all aspects of the instrument’s measurement process using any device with a web browser running under any operating system. Just as you can navigate to Yahoo! using your favorite smart device, that same device can be used without exception with the DI-808. And because intelligence is built into the instrument, third party cloud services with their associated security risks and fee-based structures are avoided entirely. You stay in control at all levels, from device configuration and real time monitoring, to the acquired data and alarms the DI-808 places on your smart device. The DI-808’s Ethernet interface allows it to integrate with any existing local area network (LAN) or virtual private network (VPN.) And simple port forwarding exposes the instrument to the Internet, allowing remote access from any location on the planet.
The DI-808 also provides four alarm output channels that can be used to flag exceptions during a recording. Each discrete output can be used to signal a PLC, turn on an alarm, or otherwise used as demanded by the application.
The DI-808 supports exceptional triggering flexibility to determine when the data logger should start and stop recording data, and when alarms should be activated.
