- Adds a KNX Twisted Pair TP1 interface and 80mA DPSU to the CloudGate
- On board Real Time Clock and microSD card reader
- USB connector and optional plug-on module for additional interfacing or 2nd KNX bus
- Built in microcontroller offloads all I/O from CloudGate
The KNX Card provides the CloudGate with a TP1 interface to a KNX installation. It can also accept a range of Option or third party developed I/O expanders that match the card to specific applications.
The KNX base board (CG1110-12012) contains a KNX TP1 interface that is connected to the front connector, labeled as KNX1. There are two LED’s and a pushbutton for status indication and configuration. There is an 80mA DPSU on board for powering the KNX1 interface. The DPSU can be enabled/disabled by a jumper setting. The status of the DPSU is indicated by a LED on the front panel. Both the KNX interface and the DPSU are galvanically isolated from the CloudGate itself.
The base board has an on board microcontroller for I/O handling and real time clock functionality. Memory expansion is possible by inserting a µSD card into a dedicated socket. There is also a USB A-type connector for additional interfacing.
Optionally the KNX base board can be equipped with a plugon module. Currently there are two plug-on modules available.
- The first one contains a second TP1 interface. This second interface can be connected via jumper settings either to the KNX2 front connector or to the KNX1 front connector in parallel with the TP1 interface on the base board itself. Also for this KNX plug on module there are two LED’s and a pushbutton for status indication and for configuration. There is a galvanic isolation between KNX2 and CloudGate and also between KNX1 and KNX2. The bus power for the KNX2 interface has to be foreseen externally.
- The second plug-on module contains an RS485 interface and a smart meter P1 port interface.
Plug on modules for KNX base board
KNX plug on
- Third-party module containing KNX TP1 interface
- Can be connected to KNX1 or KNX2 via jumper settings
RS485 plug on
- Galvanically isolated RS485 interface
- SW selectable 5V/9V/12V – 1A power output pin
- Some components on KNX base board not mounted to provide more space for I/O front connector
Other possible I/O plug on modules
- Other interfacing modules can be developed on request
- Different I/O connectors possible with dedicated front panel
- If needed the KNX base board can be understuffed to provide more space for the I/O connector
