In KNX installations, the logic module serves as a logic and control device. It has 10 logic, 10 filter/timer, 8 converter and 12 multiplexer modules. With 3 freely programmable push-buttons and 3 status LEDs. They can be assigned control and test functions and can be operated on the device. For installation on DIN rails TH35 according to EN 60715. The bus is connected using a bus connecting terminal. a data rail is not necessary. KNX software functions:. 10 logic modules (AND, OR, XOR). Each with up to 8 binary input objects and an output object. Input and output object inversion. Output disable via gate function. Behaviour of each input object after bus reset. Adjustable sending behaviour. 10 filter and timer modules. Binary input objects and an output object with time delays. Binary input object filtering before output. Output disable via gate function. Behaviour of each input object after bus reset. Adjustable sending behaviour. 8 converter modules. Conversion of 1 bit switching te
