KNX binary input 8gang 12 - 48 V AC DC potential-free REG plus REG binary inputs for connecting contacts. The switching operations of contacts (e.g. monitors or push-buttons) are converted into KNX telegrams. The inputs can be independently assigned to different functions or blocked. Signal indication via yellow status LED possible. Features: Each input has the full range of functions. All channel-oriented functions can be parameterised separately for each input. Actively transmitting telegrams of the inputs can be globally delayed after bus voltage recovery or after an ETS programming operation. Debounce time and telegram rate limitation can be configured. Free assignment of the functions switching, dimming, shutter, value transmitter and pulse counter to the inputs. Disable object for disabling individual inputs (polarity of the disable object adjustable) for the switching, dimming, shutter and value transmitter functions. Behaviour on bus voltage recovery can be parameterised separately for each input. Switching function: two independent switching objects available for each input (switching commands can be parameterised separately), command on rising and falling edge can be set independently (ON, OFF, TOGETHER, no reaction), independent cyclical sending of the switching objects can be selected depending on the edge or depending on the object value. Dimming function: 1-surface and 2-surface operation, time between dimming and switching and dimming step width adjustable, telegram repetition and stop telegram transmission possible. Blind function: Command on rising edge adjustable (no function, UP, DOWN, TURN), operating concept parameterisable (Step - Move - Step or Move - Step), time between short and long operation adjustable (only with Step - Move - Step), slat adjustment time adjustable. Value transmitter function: Edge (push-button as NO contact, push-button as NC contact, switch) and value can be parameterised for edge, value adjustment for push-button via long push-button action possible for value transmitter, light scene extension unit with memory function also possible to store the scene without prior recall. Pulse counter function: Counting interval adjustable, edge (counting on rising edge, counting on falling edge, counting on rising and falling edge) parameterisable, number of required pulses at the input parameterisable, number of required counting pulses for a counter change parameterisable, each input contains a main counter and an intermediate counter, Main counter and intermediate counter can operate separately as up or down counter, Start and end values of the counters can be preset via parameters or communication object, Query counter status via KNX or automatically, Behaviour after expiry of the counter can be parameterised, Reset pulse counter via KNX (counter reset). The binary input has eight independent inputs to which electrical signals in the voltage range from 12 to 48 V can be connected. Evaluation of direct voltage signals (DC) or alternating voltage signals (AC). The binary input provides a separate DC 24 V auxiliary voltage (SELV) for connecting potential-free contacts. Status message can be transmitted to the bus in the event of an error with the auxiliary voltage. Connection of meters with S0 interface possible (e.g. energy, gas, water meters).
