GW-IMP-WEB: Pulse counter datalogger with web interface and MODBUS protocol

The web pulse counter datalogger is capable of counting pulses on digital inputs (2 by default, expandable).

Minimum pulse duration: **10 ms**
Maximum pulse frequency: **100 Hz**

Through the web interface, it is possible to view counting values, modify the pulse weight, and enter an offset in case of misalignment or if the datalogger is installed after the counter. All data can be viewed via the web interface or accessed via MODBUS TCP connection (MODBUS RTU also available upon request). When combined with a photoreceiver, it can be used for recording totalizers of energy meters equipped with an optical pulse. The datalogger, as an optional feature, can be ordered with time-based saving of counters to a CSV file in internal memory or on an SD card. Files can be downloaded via FTP Server functionality.
