PowerBlock o16 Multi
Order no. 77024-180-05
Dimensions (L x W x H) 90 / 140 / 58 mm
PowerBlock o16 Multi is an actuator with 16 output relays with which 16 A C-loads (<140 µF) can be switched. These relay outputs can be parameterized in the ETS application as standard binary outputs or as blind or shutter outputs. "Multi" stands for the universal wiring of the outputs.
Binary switching outputs
As a binary switching actuator, channels A to H each provide 2 switching outputs. The total of 16 outputs can be connected with any loads of up to 16 A (<140 µF). Status objects can be assigned to each output. In addition, outputs can be integrated into additional functions of the application module.
Blind/roller blind application
2 outputs each form a channel (A to H) for blind or shutter control. This means that up to 8 blind or roller blind drives can be controlled with one PowerBlock o16 Multi. Each channel can be assigned status objects that signal the current position or the end position "up" and "down" (binary). Parameters define the travel time for the up and down movement and for the slat or slot opening for roller shutters. Based on these parameters, blinds and roller shutters can be controlled precisely. Blind/roller shutter channels can be integrated into the internal facade module. For facade control, additional objects are available for the corresponding facade commands up/down, position and slat position. In addition, blind/roller blind channels can be integrated into additional functions of the application module.
Fan coil control
4 outputs each form a configuration for fan coil control. Thus, one PowerBlock o16 Multi can control 4 fan coil units. An external controller supplies the control variables for controlling the valve and up to 3 fan stages of a fan coil unit. Status objects can be assigned to each output to signal the current operating status. In addition, objects provide further operating states and alarm states. The PowerBlock Multi actuators support fan coil control for both heating and cooling. Special fan coil scenes allow control of fan stages and valve via a scene object.
Installation and connection
PowerBlock o16 Multi is installed on the standard 35 mm DIN rail and has a width of 8 DU. Each output has 2 connection terminals for potential-free connection or connection of the live line and the associated switching line. For blind or shutter control, 2 outputs form one channel. For fan coil control, 4 outputs form a fan coil unit. 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.
