FOC transmitter / decoder set for incremental signals
FOC transmitters and FOC decoders are always installed when electric incremental signals are to be transmitted disturbance-free via fiber optic cables. They encode and transmit signals via a fiber optic cable to the decoder in the switchboard, where they can be used by the controller or other modules in the switchboard. In doing so they ensure high data transmission rates even over long cable lengths. Electrical isolation guarantees high levels of transmission reliability. It is possible to select HTL and/or TTL as input blocks. Optional FOC cable break monitoring is available to increase system reliability. Many Hübner Giessen encoder solutions are optionally also available with an integrated FOC transmitter.
