Remote operation on live cables and cable screens Modular power line telecontrol system Modular upgrading up to 32 stations and a maximum of 512 I/O modules Transmission on live cables up to 3 x 1000 V, 0 ... 60 Hz or cable screens of medium voltage lines Simple parameterisation of modules via DIP switch High immunity security against faults through carrier frequency technique, Hamming distance > 6 Simple connection to other transmission media, such as radio or telephone networks in the MFW product family, and also to 3rd party systems via various interfaces and protocols

A system from the MFW product family Functional description The MFW Modular Telecontrol Network has been specially designed for the interconnection of widely scattered outdoor installations, such as for example pump, transformer and gas regulating stations, storm-overow reservoirs, inspection chambers and elevated reservoirs. The MFW can be operated as a fully independent, cost-effective telecontrol system or as an extension to existing telecontrol interface modules. Almost all types of cables (telephone line, three-phase current cable, cable screen, electrically isolated cable, optical...

A system from the MFW product family The configuration of the system is very simple. All the important settings can be made with the aid of DIP switches. These include station address (1 - 31), module number (0 ... 254), static/counter value figure in the case of digital I/O and current/voltage with analog signals etc. Transmission on live cables The MFW power line telecontrol system uses for signal transmission a very safe carrier frequency technique (Hamming distance > 6) and is therefore suitable for application in rough problematic industrial environments. The MFW is suitable for...

A system from the MFW product family The bus terminals of the basic module are laid out to the direct connection at the electric line up to 500 VAC/DC. If transmission is to be on lines with voltages up to 1000 V additional coupling transmitters need to be inserted. By the insertion of coupling transmitters and repeaters the transmission medium can also be changed (e.g. from a current line to a potential-free cable and back again). For changing between lines of various levels of voltage also only coupling In some circumstances it is possible that other electrical equipment (such as...
