Description:

The IoT Wireless Datalogger is purposefully developed to capture three current inputs ranging from 0-20mA and one binary two-state input, equipped with an integrated 2G modem This innovative GSM datalogger enables the recording of three current inputs and one binary input and facilitates the sending of SMS and JSON messages via a GPRS data connection when thresholds are exceeded Collected data can be sent for storage in the COMET Cloud, which serves as a complete system for monitoring, alarming, and analysis.

A regular JSON message transmission to the COMET Database is also possible, with adjustable intervals Local alarms are indicated through LED indicators, an LCD display, and acoustic signals from a built-in beeper The device stores recordings in a non-volatile electronic memory, and data can be easily transferred to a PC using the included USB-C cable Furthermore, the GSM recorder provides a Traceable calibration certificate aligned with the metrological traceability requirements of the EN ISO/IEC 17025 standard.

Features and Benefits:

    •Records 3 current inputs (0-20mA) and 1 binary input..

    •Sends SMS and JSON messages via GPRS when limits are exceeded..

    •Collects data for storage in COMET Cloud for comprehensive monitoring..

    •Adjustable sending intervals for JSON messages to COMET Database..

    •Local alarms via LED, LCD, and built-in beeper..

    •Non-volatile electronic memory for data storage..

    •Easy data transfer to PC via USB-C cable..

    •Includes Traceable calibration certificate..
