4-way binary input, 230V~, REG, KNX. Modular binary input for connection to 230V signal generators (e.g. conventional switches, buttons, alarm generators, etc.). The device has a manual control (can also be locked) that allows the bus function to be tested independently of the inputs. The function of the LED display can be parameterized. The power failure monitoring makes it possible to distinguish between an open input and a power failure by specifying a reference input. The 230V input signals are converted independently of one another into the corresponding bus telegrams. Each input has a separate N connection and can be connected to a different phase. Functions such as lighting, blinds, roller shutters and/or heating control, and scene recall can be freely defined for each input. The device is equipped with the installation-friendly QuickConnect connection technology.
