KM6551 | Wireless data exchange terminal
The KM6551 terminal module is a data exchange unit for radio technology. The KM module is based on the IEEE802.15.4 standard. Data are exchanged or transferred via radio between two stand-alone control units, independent of the higher-level fieldbus. The outdoor range between two KM6551 units can be up to 300 m.
The data exchange module has a reverse SMA plug (Straight Medium Adapter) for connection of various radio antennas. The free choice of antenna enables adaptation to the respective environment. Status and data exchange are displayed via LEDs, thereby offering fast and simple diagnostics.
