Model DI-808 is a giant step forward in the evolution of data logger technology toward autonomous and device-independent operation. 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.
Built around the DI-808’s web server is a powerful data logger engine that adapts to a wide range of analog and pulse measurements. Eight analog input channels feature channel-independent voltage and thermocouple configurations. Voltage measurements support ±10 mV to ±50 V measurements across twelve programmable ranges. Thermocouple configurations support J, K, T, B, R, S, E, and N types. Full channel isolation allows virtually any measurement in tough industrial environments: grounded thermocouples, powered thermocouples, off-ground current shunts, as well as unexpected and unknown ground potential differences. Complementing the analog input channels are four pulse inputs. Each can be independently programmed for simple state detection, to operate as a counter, or make a frequency measurement. Use these functions to acquire, for example, volume data from a flow sensor (count), and flow rate (frequency.) Other examples are rpm measurements or simple counting in production or product life test applications. Both analog and pulse measurements are reported synchronously in the same sampling interval, and all measurements are time-and-date-stamped. Sampling intervals are pro-grammable as often as once every 25 mS or as infrequently as once every hour, with 18 selectable intervals in between. There’s even an external option to synchronize sampling to external events.
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. Each alarm output is also linked to the web interface, where an email alert (or text alert, if supported by your provider) can be triggered when the alarm activates.So, even though you may be miles from the instrument, you’re only a few swipes on your smart device away from real time process updates.
