multisio IGW - Intelligent Gateway for Energy Optimization

Our intelligent gateway multisio IGW was specially developed for the connection of controllable loads in energy optimization systems. It is therefore the perfect choice for the energy optimization integration of charging stations, battery storage units and other controllable components that provide an exchange of information via Modbus TCP/IP.

 multisio IGW

Simple integration of all controllable loads into the energy optimization system 

Whereas the loads to be controlled were previously integrated into energy optimization via hardware contacts, or usually not at all, the multisio IGW now offers a simple and convenient solution:

With the gateway, the loads are integrated into the system via Modbus TCP/IP. This protocol ensures the connection-oriented data exchange between the energy optimization system and the loads to be controlled. The multisio IGW simulates analogue and digital inputs and outputs for energy optimization. This saves you the time-consuming clarification of how the loads (charging station, battery storage etc.), which usually have standard Modbus interfaces, can be connected. Furthermore, the multisio IGW does not require an external power supply unit, as it is already integrated in the device.


multisio IGW - Intelligent Gateway for Energy Optimization


In short, the multisio IGW offers the simplest solution for including all controllable loads in the energy optimization. This gives you a fully comprehensive system with which you can effectively control your energy consumers, avoid load peaks and efficiently save energy.
