Power distribution units

The SeaZone system incorporates several power distribution units designed for different kinds of electrical functions and components. The unit at the heart of the system is called powerZone.

It has eight output terminals, safety fuses and microprocessors and can be configured/programmed to control all electrical devices and components so as to match your specific requirements. For instance, functions such as interval control, pulse and blink, minimum and maximum current strength, etc can be configured for each individual item of equipment.

You configure the system either directly in the central unit (powerZone has a small screen and four menu buttons) or via a computer. Each output terminal is protected by a safety fuse.

The system is operated either via SeaZone’s own switch panels (controlZone) or via existing Carling switches, buttons and instrument panels. To connect existing buttons and panels to powerZone, an intermediate connection is required via the power distribution unit ioZone. It connects and receives both digital and analogue signals, packeted and communicated digitally to powerZone via an ordinary network cable (CAN Bus).

If, instead, one or more of SeaZone’s panels – controlZones – are used, then an intermediate connection via ioZone will not be needed since the controlZone unit is directly connected to powerZone via a network cable. If one or more powerZone units are placed close to the electrical equipment being monitored, in the stern for instance, and controlZone and/or ioZone units are installed in the instrument panel further down the boat, then you can avoid a jungle of cables and tangled wires. This is because you only need a thin network cable to connect control instruments, buttons and the electrical devices.

powerZone 860

powerZone 860 is a programmable power distribution unit with eight output terminals, safety fuses and microprocessors that can control the boat’s electrical devices and components in any chosen configuration. In other words, you can configure each output for functions such as dimmer, interval timer, pulse and blink, on/off, etc.

For instance, the boat’s lights and defroster can be connected to the dimmer function while the windshield wipers can be controlled by the interval timer.The distribution unit is equipped with safety fuses for each output as well as an adjustable overload protector with alarm. The underload alarm can also be set to detect faults, with red light-emitting diodes signalling malfunctioning fuses, electrical equipment or components.

powerZone 860 can be configured directly in the central unit (via four menu buttons and recessed screen) or by using a computer connected to this unit via its network port. Communication is via CAN Bus interface.

Instrument panels, Carling switches and other control instruments are connected via ioZone. Up to three powerZones can be serially connected to, and controlled by, one ioZone, giving a total of 24 outputs. However, there is in principle no upper limit as to how many powerZones that can be serially connected. SeaZone’s own instrument panels, controlZone, are directly connected via a network cable.

ioZone 24D

ioZone 24D is a power distribution unit that connects and relays digital and analogue signals from Carling switches, buttons and instrument panels to powerZone. Here, the signals are interpreted and the pre-programmed instructions for the electrical devices are carried out.

ioZone 24D has 24 digital input terminals and a recessed screen that displays active signals and input sockets.

Communication with powerZone is via a network cable (CAN Bus).

ioZone 24DA

ioZone 24DA is a power distribution unit that connects and relays digital and analogue signals from Carling switches, buttons and instrument panels to powerZone. Here, the signals are interpreted and the pre-programmed instructions for the electrical devices are carried out.

ioZone 24DA has 12 digital and 8 analogue input terminals and 4 terminals that can be used for digital inputs or outputs. There is also a recessed screen that displays active signals as well as status readings for inputs and outputs.

Communication with powerZone is via a network cable (CAN Bus).
