3 Product Overview
3.1 Product Overview
The devices are of type modular DIN rail component (MDRC) in Pro M design. The module width of the
devices is six space units. They are designed for installation in distribution boards on 35 mm mounting
rails.
The devices are powered by the bus and require no additional auxiliary voltage supply. The device
connects to the ABB i-bus®KNX via the front bus connection terminal.
Engineering Tool Software (ETS) is used for physical address assignment and parametrization.
The device is ready for operation after connecting the supply voltage.
