KeyBox CANbus Relay Module

KeyBox is a compact I/O CAN-bus relay module designed to control 12V or 24V electrical loads. It enables efficient management of powered components such as lights, electric motors, bilge pumps, mechanical arms and other onboard devices.

The module can be connected to Blink Marine PowerKey and PowerKey Pro series keypads, allowing intuitive CAN-bus control of multiple electrical functions. KeyBox is ideal for vehicle and marine installations where additional outputs or distributed control modules are required.

With 13 fused circuits with integrated relays, KeyBox allows reliable control of multiple electrical loads. Multiple modules can be connected in sequence and controlled via a single CAN communication bus together with one or more Blink Marine keypads.
