Level Converters HTL >>> TTL / RS422 resp. TTL / RS422 >>> HTL, Potential Separators and Direction Decoders

The motrona level converters, directional decoders and potential separators ensure maximum flexibility, because they are able to convert the encoder signals from incremental encoders into a different format. Depending on the device type, you can transform the signals from HTL encoders to a TTL / RS422 format or vice versa. The type PU210 already contains both conversion forms and also has a potential separation between input and output. In addition, these devices have a directional output that allows directional information about the phase offset, via a static signal or via separate channels (forward / reverse). The cabinet installation is quick and easy by snap-on housing for top hat rail (according to EN 60715).

Universal interface using with incremental measuring systems.
