IF11 is designed for contactless (non mechanical), bounce-free switching between two SSI encoders and one SSI Master unit.
The switching operation is under control of a remote signal (HTL, 24 V). Moreover, there is an automatic internal synchronization to the next SSI signal pause, avoiding fragmented SSI telegrams and wrong information while commutation is in progress.
Typical applications can be found in handling and conveyor technology, where one Master unit must evaluate the signals of two independent SSI encoders for summing or differential information. We can find applications also in drives and automation, such as automatic roll change “on the fly” or redundant systems using several encoders for safety requirements.
IF11 uses a narrow and space-saving plastic housing, suitable for DIN rail mounting (according to IEC/EN 60715). Two LEDs are mounted on the front panel for easy diagnostics.
