Kirjeldus
The RS485/PROFIBUS LWL T-coupler reroutes the PROFIBUS from copper conductors to optical waveguides. The LWL T-coupler is a passive bus participant. In plants, the LWL T-coupler allows the bridging of great distance with PROFIBUS without noice interference.The electronics for the signal conversion are accomodated in the flameproof MODEX enclosure. Transmitter and receiver for the LWL-coupler are intrinsically safe headed. The intrinsically safe control transmitter and receiver of the electronic system guarantee that the transmitter rate does not go beyond maximum value limits.
