Description

The DT82I Industrial Data Logger

The new DT82I Industrial Data Logger Series 4 version has increased sampling speed, measurement range, and programmable analog output.

The DT82I smart data logger provides an extensive array of features that allow it to be used across various applications. The DT82I is a robust, stand-alone, low-power data logger featuring USB memory stick support, 18-bit resolution, extensive communications capabilities, and a built-in display.

The dataTaker DT82I’s Dual Channel concept allows up to 4 isolated or 6 commonly referenced analog inputs to be used in many combinations. With support for Modbus for SCADA systems, FTP and Web interface, and 12V regulated output to power sensors, the DT82I is a self-contained solution.

Versatile Measurement

Connect an array of sensors through versatile analog and digital channels, high-speed counter inputs, and programmable serial sensor channels.

Temperature, voltage, current, 4-20mA loops, resistance, bridges, strain gauges, frequency, digital, serial, and calculated measurements can all be scaled, logged, and returned in engineering units or within statistical reporting.

Set up sampling, logging, alarm, and control tasks to suit your requirements while interfaces for smart sensors, GPS, and other intelligent devices expand the DT82I flexibility.

Easy Data Management & Communication

With the standard unit able to store up to 10 million data points (expandable) you can log as much or as little as you need. Overwrite or stop logging once allocated memory is full, archive data on alarm event, copy to USB memory or transfer via FTP/ Email, the choice is yours.

Communications features include RS232 and Ethernet, and connect to the DT82I locally, remotely through a modem, or over the Internet.
