forward and reverse relay module

Motor Reversing Module

Part No:  2300-1001-A (No Hardware)

Part No:  2300-1001-B (w/ Hardware)

Built for precision control, this motor reversing module safely and efficiently switches polarity for DC motors. It enables smooth forward and reverse operation while protecting circuits from overload and reverse-current damage.

Whether you’re running trim tabs, hatch lifts, actuators, or winches, this relay module ensures dependable bidirectional control in marine, RV, and industrial systems.

Why You Need It:

 

  • Essential for Push Button Switches: Prevents voltage drop and ensures full power delivery

  • Flexible Compatibility: Works with rocker switches, push buttons, and more

  • Dynamic Braking: Motor stops instantly when the switch is returned to OFF

  • Reliable Power Flow: Eliminates performance loss from voltage drops

Common Applications:

 

  • Trim tabs and hatch lifts

  • Hoists and winches

  • Tarp and lift systems

  • Intake/exhaust fans and vents

Key Specs:

 

  • Load Rating: 50A at 12VDC (intermittent) | 30A at 12VDC (continuous)

  • Construction: Rugged, sealed, and potted to IP67 waterproof standard

Frequently Asked Questions (FAQ)

What is a motor reversing module?
A motor reversing module (also called a forward and reverse relay or reverse polarity module) is a voltage-control device that changes the direction of a DC motor. It allows a motor to run forward or backward safely, while protecting circuits from overload or reverse current.

Do I need a relay module for trim tabs?
Yes. For push button switches in particular, a motor reversing relay is essential. Without it, you risk voltage drop and unreliable trim tab operation. It ensures smooth movement and stops the motor instantly when the switch is off.

Can this relay work with rocker switches?
Yes. While the module is a necessity for push button systems, it can also be wired with rocker switches. For motor reversal with rockers, we recommend following proper wiring diagrams for best results.

Is this relay waterproof?
Yes. The unit is IP67 rated, fully sealed and potted, making it suitable for saltwater and other harsh environments. It’s marine-grade with tin-plated brass studs for corrosion resistance.

What size motor can it handle?
The module runs up to 50A at 12VDC (intermittent loads) and 30A at 12VDC (continuous loads), making it suitable for trim tabs, hatch lifts, winches, hoists, fans, and more.

What’s the difference between a motor reversing relay and a reverse polarity module?
They’re the same device. Different manufacturers use different terms, but all refer to the same function—switching polarity to reverse DC motor direction.

Can I install it myself?
Many DIY boat owners install this relay themselves. However, for complex multi-motor systems or integrations with advanced switch panels, a professional installer is recommended.
