Problems solved by technology

[0010] However, each connection terminal requires a corresponding construction space, so that the connection area of ​​the controller is relatively large
In addition, there is a risk of confusion over connection terminals due to the various connection possibilities
This can lead not only to functional failures in the controller, but also to damage or destruction of connected sensors / devices or damage or destruction of electronic components of the controller connected to the corresponding connection terminals

Embodiment Construction

[0078] figure 1 A first variant of a circuit arrangement 1 according to the invention for a controller of a construction installation, in particular for a control and regulation electronics of a pump installation, is shown. The circuit arrangement 1 has a multifunctional input 2, to which various components 31, 32, 33, 34 (here sensors) can be connected, which have different output signals I E , U E , U T , U PWM . The output signal can be considered as a measurement or control signal here. The input 2 comprises two connections 2a, 2b, of which the second connection 2b is grounded. The first connection 2a conducts the actual output signal and is wired internally for processing the output signal.

[0079]The circuit device 1 comprises a first analog-to-digital converter (ADC) 3, a first low-pass filter 11 and a voltage divider 6, wherein the first ADC3 is connected to the first ADC 3 via the low-pass filter 11 and the voltage divider 6 The input 2 or the first connection...

Abstract

The invention relates to a circuit arrangement (1) for a controller of a construction device, in particular a control and regulation electronics of a pump device. The circuit arrangement is used for processing output signals (UE, IE, UT, UPWM, U1W) of devices (31, 32, 33 , 34, 35); the circuit arrangement has a multi-function input end (2); the multi-function input end comprises two connection ends (2a, 2b) for connecting the devices (31, 32, 33, 34, 35). The circuit arrangement can operate in at least two different modes, and at least three different device types with different kinds of output signals can be connected to the input end (2). Here, there is an internal line of the input end (2), and the internal line has at least one controllable switch for changing the internal line according to the type of the connected device.

Description

technical field [0001] The invention relates to a circuit arrangement for a controller of a construction installation, in particular for control and regulation electronics of a pump installation, for processing output signals of the device, the circuit arrangement having a multifunctional input Terminal, the multi-function input terminal includes two connection terminals for connecting devices. In particular, the invention relates to inputs for connecting different sensors of different sensor types to a controller. Furthermore, the invention relates to a method for determining which component type is connected to a circuit arrangement. Background technique [0002] Controllers of building automation systems usually have control or regulating functions which are dependent on measurement signals of specific sensors or external control signals (for example as setpoint values) of other components of the building automation system (for example superordinate control components). ...
