Hardware Functions of the Control Unit

Modular design – designed for industrial use
The modular design of the control unit allows it to be flexibly adapted to the requirements of various industrial applications. The system can be easily customized with digital and analog I/O modules, communication interfaces, and special extensions, thus always offering an optimized solution for the task at hand.

The device complies with industrial EMC standards, ensuring a high level of interference immunity against electromagnetic effects and network disturbances. This makes it reliable for use in industrial environments where continuous operation and stable data connections are essential requirements. Thanks to its DIN rail mountable design, it can be easily integrated into existing cabinets and industrial infrastructures. Its long-term availability and scalability make it the ideal choice for projects where flexibility, operational reliability, and cost-effectiveness are all important considerations.

2 Ethernet interfaces - separate Internet and intranet
The control unit has two separate Ethernet ports, which allow the Internet and intranetnetworks to be separated. One port provides internet connectivity – for example, for remote monitoring, data transmission, or access to cloud services. If required, controlled devices can also be connected to this network, giving them direct internet access for their own monitoring systems or software updates.

The other port, on the other hand, allows for the creation of a separate, protected internal network (intranet). When controlled devices are connected here, they do not have Internet access, which ensures a higher level of security. This is particularly advantageous in industrial environments where network policies strictly limit Internet access to internal systems.

Separating the two ports thus guarantees secure and uninterrupted local control, while maintaining flexibility for providing Internet access as needed.

Digital IO module - direct control and status monitoring
The digital I/O module enables direct control of various industrial devices and status feedback. The inputs and outputs, which operate at a signal level of 24 V, ensure simple and reliable integration into control cabinets, safety elements, or dedicated consumers.

Using logic based on I/O signals, the system can control automated processes, such as starting a hot water production unit or a cooling compressor in the event of excess solar energy. It is also suitable for switching motor circuit breakers on and off and providing feedback on their current status.
