Alarm meters / indicators with GSM-logger function (I4l-GSM, I8l-GSM, I16l-GSM, I32l-GSM)

Alarm meters / indicators with GSM-logger function are designed to work with sensors that have an RS-485 output (ModBus RTU protocol) and display the measured values on a liquid crystal display. GSM loggers can be 4, 8, 16, or 32 channels.

General functions and operating modes

• indication of values measured using sensors with RS-485 output from 1 to 32 channels;
• formation of the "Alarm" signal when the controlled parameter goes beyond the permissible limits;
• sending SMS in case of emergency to specified numbers;
• calling a subscriber in case of an emergency;
• saving measured values into non-volatile memory at specified time intervals;
• built-in digital real time clock (storage of measured values with time reference);
• automatic correction of hours per day for a specified time;
• data exchange with a personal computer (setting internal parameters) via the USB interface;
• data transfer to FTP server using GPRS connection;
• switching on the output device in case of an emergency;
• control of the output device via SMS;
• the ability to send status SMS by SMS request;
• power supply from a 24V constant voltage source.
• 4-channel device can store 59500 values in internal memory;
• 8-channel device can store 59500 values in internal memory;
• 16-channel device can store 53,200 values in internal memory;
• 32-channel device can store 28650 values in internal memory;
