CI-tronic™ Reversing contactor
Type RCI
RCI reversing contactors are designed for demanding forward/reverse control of three-phase AC motors. The zero cross switching method ensures very fast and precise motor control and virtually eliminates EMC emission. The RCI reversing contactor is ideal where fast switching capability and long life are essential. Typical applications are conveyors, thread cutting machines, packaging lines and other applications where fast reversing capabilities are needed.

Functional description |
When control circuit A1 – A2 is ON, the motor will |
|
rotate forward. With control circuit A3 – A4 ON |
|
the motor will rotate in reverse direction. If both |
|
control circuits are switched ON the motor will |
|
rotate in the direction determined by the circuit |
which was switched ON first. A delay time (interlock) between forward and reverse running is incorporated.
