The iSMA-B-MG-IP device has been designed to simplify the connection of meters installation with BMS. By applying the most popular interfaces for M-Bus and Modbus meters, the device allows to handle up to 180 meters of various types simultaneously. The M-Bus interface allows to communicate and supply with power up to 60 M-Bus meters. The maximum current may not exceed 130 mA. The RS485 interface allows to connect up to 128 Modbus devices. The device address and baud rate for Modbus are set by using DIP switches. The built-in TCP/IP interface provides the ability to use the existing LAN infrastructure, also allows to build a scattered meters monitoring system. iSMA-B-MG-IP device configuration is possible from the built-in web services level, and by using free tool such as iSMA Configurator.
