Spacelogic KNX Coupler DIN Rail. For logical connection and electrical 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 both 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 a galvanic separation between the lines. The coupler supports KNX longframes and is compatible with the ETS 5 software. With 2 integrated push-buttons for testing purpose and 3 status LEDs. For installation on DIN rails TH35 according to EN 60715. The bus is connected using bus connecting terminals. KNX software functions - The device can be used as a area / line coupler or as a repeater for forming line segments in existing or new KNX systems. The function as a coupler or repeater can be parameterised. Functions as coupler - Use as a 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 area (Group 0-31) with filter function. Forwarding of individually addressed telegrams (subline = mainline, mainline = subline) can be parameterized. Forwarding of group telegrams (subline = mainline, mainline = subline) can be parameterized. Telegram repetitions in the event of transmission errors can be set separately for group telegrams, broadcast telegrams and physically addressed telegrams. Telegram confirmation for group telegrams and physically addressed telegrams can be parameterised separately. Functions as repeater - Expansion of a line into segments. Telegram repetitions in the event of transmission errors can be set separately for group telegrams, broadcast telegrams and physically addressed telegrams. Device width - 1 modules = approx. 18 mm. Note - This application requires ETS 5 or higher. Contents - With 2 bus connecting terminals and 2 cable cover.
