Modular binary input for connection to 230V signal transmitters (e.g., conventional switches, pushbuttons, alarm devices, etc.). The device features manual operation (which can also be locked) that allows testing of the bus function independently of the inputs. The LED display function can be parameterized. Mains failure monitoring allows differentiation between an open input and a power failure by specifying a reference input. The 230V input signals are converted independently into the corresponding bus telegrams. Each input has a separate neutral (N) connection and can be connected to a different phase. Functions such as lighting, blind, shutter, and/or heating control, and scene recall are freely definable for each input. The device is equipped with the user-friendly QuickConnect connection technology. Key features: Module type: Digital; Signal detection: Input; Number of channels: 4; Number of digital channels: 4.
