The high voltage inputs of the InBlock i8 HV evaluate potential input signals. The signals voltage ON and voltage OFF are processed to KNX signals which are then available on the KNX bus. Thus, each input signal can be evaluated as an ON/OFF signal, as a dimming signal with the evaluation of a long and short button press and as a blind signal. The multiple triggering of an input signal can be counted, so that the counted number can be assigned to a KNX function. Each input can thus also be parameterized as a pulse counting input. In addition, the input signals can be integrated into additional functions of the application module.
Installation and connection
InBlock i8 HV is installed on the standard 35 mm top-hat rail and has a width of 4 DU. Each input has 2 connection terminals for connecting the live line and the associated signal line. The KNX bus connection is made via the standard bus connector.
This module enables the configuration of 10 scenes with a maximum of 8 objects each. 1 Bit, 1 Byte, 2 Byte and 4 Byte objects can be configured as scene objects. Objects can also disable a scene. Any events can start and save a scene. The execution of a scene can also be stopped via an object and a further object enables the restoration of a scene to its original values.
Up to 8 events can be assigned to alarms. These include analogue values such as temperature or binary status objects which, in connection with a threshold value, trigger the alarm. As a typical alarm logic, the function can be set up in such a way that alarms are acknowledged via separate objects.
Special objects count the time of closed contacts in order to determine, for example, the running time of a machine.
With just a few parameters, easy-to-use staircase functions with running time extensions and expiration warnings as well as switch-on and off delays can be configured. Timers can be activated and de-activated via additional objects.
With the logic module up to 35 logic gates can be configured. Each gate has a maximum of four inputs and one output. To select the logic function, “AND“, “OR“; “XOR“, NOT functions, gate functions, mathematical operators such as adders, subtractors, multipliers and dividers, comparators such as “greater than“, “„less than“, “equal to“ and converters for data type transformation are all available. Data point types can be configured depending on the logic function.
This module makes it possible to count incoming events. Each event can be given a factor, so that it can be counted in relation to a certain value. At the same time, a particular number of events can be assigned to a value. Each counter can be assigned threshold values which will trigger an alarm when the threshold is reached. The counter can be re-set via an object.
The application allows for the configuration of up to ten 2-point controllers. For each controller an activation object, objects for current and set value, heating and cooling mode and a binary controller output are available. In connection with the KNX data point type operating mode, individual controllers can be easily switched on and off.
