Relay Module - 12VA Relay Module reduces voltage drop in Trim Tab Systems with longer wire runs. With the older trim tab controls, RT1000 and RS1000, the Relay Module also functions as an Interrupter Relay and will prevent a fuse from blowing if Bow Down and Bow Up are inadvertently pressed at the same time.
