iSMA-B-MG-IP is designed to simplify the connection of meters installation with BMS. It is equipped with the most popular interfaces for M-Bus and Modbus meters, the meter gateway allows to handle up to 180 counters of various types simultaneously.
The M-bus interface allows to communicate and power up to 60 M-Bus meters, the maximum current can not exceed 130 mA.The RS485 interface allows to connect up to 128 Modbus devices.
The device can be configured using DIP switches, built-in web service and our tool iSMA Configurator.
