Keybox Relay Modules

Keybox is a CAN bus relay module for electric loads designed by Blink Marine specifically for use in vehicles and boats. It is a small device which, once it’s connected to various utilities (lights, electric motors, bilge pumps, mechanical arms), allows you to use Blink Marine keypads to control them.

This compact and versatile smart relay module for electric loads permits the utilization of Blink Keypads where there are no PLC systems on board. By utilizing its CAN bus interface and high power outputs, Keybox can be used in “slave” mode with complex systems.
