Description

The RS485/PROFIBUS Optical Fibre T-coupler reroutes the PROFIBUS from copper conductors to optical fibres. The coupler is a passive bus participant. The optical fibre T-coupler allows great ranges to be bridged in plants using PROFIBUS, and is resistant to interference. The electronics for the signal conversion are accomodated in the flameproof MODEX enclosure. The transmitter and receiver for the optical fibre T-coupler are activated in an intrinsically safe way, thereby ensuring that the transmission power of the transmitter does not exceed the permitted limits.
