JURPLIX Forward/Reverse Relay Module 2-Pack 12V 80A/50A, Heavy-Duty Brass Studs Rust-Resistant

JURPLIX 12V Forward and Reverse Relay Module is a heavy-duty motor direction controller that lets you switch motor rotation reliably for winches, lifts, vents and other 12V systems.

This compact relay pair provides the electrical switching required to reverse DC motors safely and efficiently. Built for rugged automotive, marine and industrial use, the modules are offered as replacements for part numbers such as 5541100 and 24452. They combine brass studs and rust-resistant materials with clear mounting points so installers can retrofit or upgrade existing directional-control circuits.

How does this relay module reverse a 12V motor?

The module contains two relay units wired to swap polarity to the motor when triggered, enabling forward and reverse rotation without manual rewiring. Each relay uses heavy studs and internal contacts sized for high-current switching, ensuring the motor sees a clean polarity change during direction shifts.

• Uses two relays to alternate power polarity to the motor terminals.
• Brass M6 and M5 studs for secure high-current connections.
• Designed for 80A intermittent and 50A continuous duty ratings.

What equipment can this module be used with?

It’s intended for 12V systems that need reliable directional control, such as tarpaulin drives, truck and boat winches, jack lifts, hatches, trim tabs and ventilation fans. The module fits into both new projects and existing installations where the listed OEM part numbers are specified.

• Compatible with winches, tarpaulin motors, jack lifts, hatches and trim tabs.
• Suitable for marine and automotive 12V environments with corrosion resistance.
• Replaces OEM parts 5541100, 24452, ATP0110, K10746M and 13994.

What are the electrical and mechanical specifications?

Each module is rated for heavy-duty use: up to 80A for intermittent operation and 50A continuously at 12VDC. Mounting is handled via four M6 and two M5 studs—plan to use matching ring terminals and ensure fasteners are torqued to a secure, vibration-resistant setting.

• Operating voltage: 12 VDC.
• Current rating: 80A intermittent, 50A continuous.
• Terminals: 4 × M6 studs and 2 × M5 studs; use M6/M5 ring terminals.

How durable and safe is the relay module?

The unit is constructed from rust- and moisture-resistant materials and uses brass studs to reduce corrosion and improve conductivity. That build quality extends service life in damp or salty environments and lowers the chance of poor connections that cause heating or arcing.

• Rust- and moisture-resistant housing for longer outdoor service life.
• Brass studs for improved corrosion resistance and electrical contact.
• Designed to respond quickly for precise motor direction control.

Who is this for: technicians, mechanics and DIY installers who need a dependable replacement directional relay for 12V motors. If you maintain truck tarpaulin systems, marine winches, hydraulic jack lifts, hatches or ventilation motors and you require a durable, OEM-compatible forward/reverse control, this JURPLIX module pair is built for retrofit and repair projects where reliable switching and corrosion resistance matter.
