Bennett 12V Relay Module for Trim Tab Systems (RM12)

The Bennett 12V Relay Module (RM12) is designed to reduce voltage drop in electric trim tab systems that have longer wire runs between the helm control and the actuators. As wiring distance increases, voltage drop can slow tab response and reduce system performance; the Relay Module compensates for this by handling the higher-current switching closer to the actuators, keeping tab response consistent.

For boats running Bennett's older trim tab controls, the RT1000 and RS1000, the Relay Module also serves a second function as an Interrupter Relay. In this application it helps prevent a fuse from blowing if the Bow Down and Bow Up buttons are inadvertently pressed at the same time, protecting the wiring and control circuit from a short-duration electrical conflict.

The module is built for wired, boat-mount installation with copper contacts and normally-open contact operation, running on a 12 volt DC coil and switching circuit. It operates automatically once wired into the system and meets ABYC electrical standards, making it a straightforward add-on for boaters extending or upgrading an existing Bennett electric trim tab installation.

Frequently Asked Questions

What does the Bennett RM12 Relay Module do? The Bennett RM12 12V Relay Module reduces voltage drop in electric trim tab systems that have longer wire runs, keeping tab response consistent between the helm control and the actuators.

Is the RM12 compatible with older Bennett trim tab controls? Yes. With the older Bennett RT1000 and RS1000 trim tab controls, the RM12 Relay Module also functions as an Interrupter Relay, helping prevent a fuse from blowing if Bow Down and Bow Up are pressed at the same time.

What voltage does the Bennett RM12 run on? The RM12 operates on a 12 volt DC coil and switching circuit, with a minimum and maximum switching voltage of 12 volts.

How many terminals does the RM12 Relay Module have? The Bennett RM12 has 3 terminals for wiring into the trim tab system's electrical circuit.

What are the contacts made of on the RM12? Copper contacts are used in the Bennett RM12, configured as normally open, with automatic operation once wired in.

How is the Bennett RM12 mounted? The RM12 is a boat-mount, wired relay module rather than a plug-and-play inline unit, so it is installed and wired directly into the boat's trim tab circuit.

How much does the Bennett RM12 weigh? The Bennett RM12 Relay Module weighs 0.5 pounds.

What are the package dimensions of the RM12? The Bennett RM12 Relay Module ships in a package measuring 6.0 inches long by 4.0 inches wide by 5.0 inches high.

Does the RM12 meet any marine electrical standards? Yes, the Bennett RM12 Relay Module meets ABYC electrical specifications.

Why would I need to add a relay module to my trim tab system? A relay module like the Bennett RM12 is added when wire runs between the helm control and trim tab actuators are long enough to cause voltage drop, which can slow or weaken tab response without it.

Where is the Bennett RM12 manufactured? The Bennett RM12 Relay Module's country of origin is the United States.
