What is "instabus"

Instabus, is a decentralized open system to manage and control electrical devices within a facility. It is developed by Berker, Gira, Jung, Merten and Siemens AG. There are about 200 companies of electrical supplies using this communication protocol. The EIB (European Installation Bus) allows all electrical components to be interconnected through an electrical bus. Every component is able to send commands to other components, no matter where they are. A typical EIB network is made of electrical components such as switches, pulsers, electric motors, electrovalves, contactors, and sensors.

This electrical bus is made of a 2x2x0,8mm twisted pair cable, that connects all devices within the network. The theoretical maximum number of components is 57375.

EIB system was developed to increase power savings, security, comfort and flexibility.
