Measuring, Monitoring and Control System
The Pacific is a measuring, monitoring and control system designed for use in fish farms
It is both multichannel and multi-parameter, and forms a modular small size complete system. A member of the Commander series of equipment, it can be used both as a stand-alone system or as part of a larger Commander system.
An important feature of Pacific is its extensive connection capabilities. It has P-NET data bus for connection to other Commander components, IP connection for LAN or internet, modbus interface and two USB ports that can be used for a number of purposes. It also has an SD card socket for data interchange.
An additional feature is the option that enables Pacific to connect to a Wireless Probe system, where the various probes and other measuring, monitoring and control devices interconnect using wireless signals.
Pacific brings the complete functionality of Commander to small systems and to installations where few measurements and points of control are situated at large distances from each other.
The smallest systems consist of a Pacific Main Unit and some probes. The Main unit has terminals for various inputs and outputs and has 6 relay outputs. The result is a measuring, monitoring and control system with data logging with data bus, USB and IP ports Pacific is easy to access. It also comes with memory card socket for long term data storage.
You can wire 4 probes directly to the Main unit. Input boxes and output boxes are used for further wired connections. On/off inputs can be 2-state from, for example, level switches or pulsed from flowmeters.
Pacific is ideal for sea cages. Remote access to the Pacific unit on the feed barge can be made, for example, using wireless LAN or through a wireless internet connection.
A Pacific System consists of a Main Unit, other units, probes and power supplies as needed. A single system can have 20 probes or analogue inputs, 30 relays and 30 on/off (digital) inputs or outputs. All Pacific units use 24V DC power from one or more power unit.
The Pacific Main Unit has terminals for 4 probes, 6 on/off inputs or outputs, 6 output relays, each with single pole changeover contact and a touch screen display.
The Pacific Combi Unit has terminals for 4 probes, has 6 on/off inputs or outputs and
6 output relays, each with single pole changeover contact.
The Pacific Analogue Unit is for 8 analogue inputs. These can be from active or passive
devices. The Pacific Analogue unit can provide 24V DC to the devices.
The Pacific Digital I/O Unit is for 8 on/off signals, either inputs, outputs or a combination
of both, and also has 8 relays, each with single pole changeover contact.
The Pacific Probe Unit is for the wired connection of 8 probes. Probes for DO &
temperature, pH, redox (ORP), salinity, CO2 and TGP can be connected directly to a
The Pacific Power Supply can deliver 5A and has back-up batteries, one power supply is used for each unit.
