Modular binary input for connection to 230 V signal generators (e.g. conventional switches, pushbuttons, alarm devices etc.). The device is equipped with a manual control (also lockable), which allows the bus function to be tested independently of the inputs. The function of the LED display can be configured. Power failure monitoring allows a distinction between open input and power failure by specifying a reference input. The 230-V input signals are converted into the corresponding bus telegrams independently of each other. Each input has a separate N connector and can be connected to a different phase. Functions: Lighting, blinds, roller shutters and/or heating control and scene recall can be freely assigned to each input. The device is equipped with installation-friendly QuickConnect connection technology. https://elecena.pl/product/26103781/txa304-binary-input-4-channel-230-v-reg-knx 2024-06-20 https://elecena.pl/product/26103781/txa304-binary-input-4-channel-230-v-reg-knx 2025-04-06
