iSMA-B-MG-IP

​

iSMA-B-MG-IP was developed to simplify the connection of meters to building management systems. Using the two most popular communication protocols (M-Bus and Modbus), it enables the simultaneous management of up to 180 different types of meters. The device's M-BUS interface is capable of powering 60 M-BUS devices and communicating with them. The maximum current consumption cannot be more than 130 mA.

​

The RS485 interface 128 can handle Modbus devices.

​

The built-in TCP/IP interface makes it possible to use the device on the existing LAN infrastructure and to build extensive monitoring systems with its help.

​

The configuration of the iSMA-B-MG-IP device can be done through its built-in web interface, but also with the free iSMA Configurator software.

Main features:

  • M-Bus TCP/M-Bus gateway

  • Modbus TCP/IP/ Modbus RTU/ASCII gateway

  • Up to 180 different types of meters

  • The two different gateways work in parallel in the device. 

  • Built-in power supply for supplying 60 M-Bus meters

  • Direct connection to up to 6 M-Bus branches

  • Built-in Mini USB port for configuration and device firmware update.
