Telemetry device GL2A7D7C is the device intended for collection of metering and control information for the purpose of monitoring, tracking and reading of digital and analog signals. The device is powered by 12V DC voltage and due to its very low consumption it is suitable for installation of systems powered by renewable power sources. His application is possible in various fields of measurement and control such as monitoring and reading of various meters (water, electricity, gas, flow, temperature, pressure, monitoring sensors, detection of access, etc.).

Telemetry device GL2A7D7C collects information on the state of digital and analog inputs, recording them in the internal memory, and with use of GPRS module periodically forwarding them to a remote server (FTP server). The data is delivered to a remote server (FTP server) in XML format that allows easy integration of devices in any database or application.

GL2A7D7C is equipped with two analog inputs 0-20mA which enable gathering of information from various sensors (pressure, flow, temperature, etc.) and seven digital inputs which enable gathering information from the motion sensors, fracture sensors, various contact alarm sensors etc. All digital inputs have volume counters 999999999 and speed 100 Hz, which allows us to gather information about the various counters (water meters, gas meters, electricity meters, work hours meters, operation counters, etc.) The first digital input has a frequency counter speed of up to 50000 Hz.
All inputs have the possibility of setting the parameters for SMS alarms in case of deviations from the set points.

GL2A7D7C is equipped with two batteries, one of which is CR2032 and serves to maintain the RTC, and the other is rechargeable, type 18650, which is used for the smooth operation of the counter in case of electric power failure.
