Reverse Polarity Contactor Wiring Diagram

25+ Reverse Polarity Contactor Wiring Diagram Background. The forward reverse motor control is used in a system where forward and backward or upward and downward movement in the operation is needed. This is achieved by integrating two dc contactors into a single housing unit, eliminating many costly materials and streamlining final product assembly and wire connection.

A external battery contactor can be easily added to the 4qd series. Using a diode as reverse power polarity protection as shown in circuit 1 is a very simple and reliable solution as long as you can afford the waste of power. Reversed polarity on an electrical outlet is dangerous.

I would set this up in a test scenario (loose parts on a table), and once you have it figured out, you can start attaching things to your actual motorized slider.
