Spacelogic KNX coupler on DIN rail. For logical connection and galvanic isolation of lines and areas. The device supports KNX Security. This option can be activated in the ETS. As a secure line coupler, the device enables the forwarding of secured and unsecured communication. In addition, access to the device itself (e.g. for a download) is protected by KNX Security. The device has a filter table (8k bytes) and ensures galvanic isolation between the lines. The coupler supports KNX long frames and is compatible with the ETS 5 software. With 2 integrated buttons for test purposes and 3 status LEDs. For mounting on TH35 top hat rails according to EN 60715. The bus is connected via bus connection terminals. KNX software functions - The device can be used as an area/line coupler or as a repeater to form line segments in existing or new KNX systems. The function as a coupler or repeater can be parameterized. Functions as a coupler - Use as an area or line coupler depending on the physical address. Reduction of the bus load through the filter function (filter table). Support of the full address range (group 0-31) with filter function. The forwarding of individually addressed telegrams (subline - mainline, mainline - subline) can be parameterized. The forwarding of group telegrams (subline - main line, main line - subline) can be parameterized. Telegram repetitions in the event of transmission errors can be parameterized separately for group telegrams, broadcast telegrams and physically addressed telegrams. The telegram confirmation for group telegrams and physically addressed telegrams can be parameterized separately. Function as a repeater - Extension of a line into segments. Telegram repetitions in the event of transmission errors can be parameterized separately for group telegrams, broadcast telegrams and physically addressed telegrams. Device width - 1 module approx. 18 mm. Note - This application requires ETS 5 or higher. Contents - With 2 bus connection terminals and 2 cable covers.
