IoT Wireless Datalogger for 3 current inputs 0-20mA and 1 two-state input, with built-in GSM modem and Flat Rate SIM Card

IoT Wireless Datalogger kit with built-in GSM modem and Flat Rate SIM Card allows the instant connection to the COMET Cloud.

Measured values can be sent to the internet storage COMET Cloud, which is a complete monitoring, alarm and analysis system. IoT Datalogger is designed to record 3 current inputs and 1 binary input. In case of exceeded set limits, SMS and JSON messages can be sent via GPRS data connection.

It is also possible to set the regular sending of JSON messages to COMET Database, the sending interval is adjustable. Alarms are also indicated locally by LED, LCD and acoustically by built-in beeper.
The recording is performed in a non-volatile electronic memory. The data can be transferred to a PC via included USB-C cable.

GSM recorder includes Traceable calibration certificate with declared metrological traceability of etalons is based on requirements of EN ISO/IEC 17025 standard.
